STARVIS means you can see very dim stars in real time video. The QHY5III290 can capture magnitude 9 stars with a 50mm F\/1.4 C-mount lens.  Compared to the IMX236 sensor, for example, the IMX290 has twice sensitivity for visible light and three or more times the sensitivity in near infrared.  The QHY5III290 also has ultra low read noise.  The back-illumination and low read noise make this camera an ideal video astronomy camera.  The small 2.9um pixel size is also ideal for planetary imaging.  The QHY5III290 has a fast USB 3.0 interface and produces 135FPS at full HD output . The camera has 10\/12-bit ADC and it outputs an 8-bit or 12-bit image.

The camera is designed to be an excellent planetary, lunar, solar and meteor capture video camera. With a 50mm, F\/1.4 C-mount lens it will record 8th to 9th magnitude stars at 30 frames per second (33 ms exposure).  This high sensitivity with HD resolution will push video astronomy to new heights.  Sony introduced a new global shutter (GS) CMOS imaging technology called PregiusTM that redefines the global shutter imaging category and provides the best of both worlds:  fast frame rates and CCD-like imaging performance.  The technology also offers reduced dark noise, which enables higher gains without compromising image quality, as well as higher quantum efficiency.    The global shutter eliminates pixelization when imaging the moon and planets and moon caused by atmospheric agitation and high frame rates. \u003c\/p\u003e\u003cp\u003eThe unique QHYCCD design retains the 1.25-inch eyepiece design of the QHY5-II series but adds features for better cooling.  This design is more efficient in transfer of heat to the outer case enabling lower noise especially in high ambient temperatures.  The 1.25 inch design also offers the shortest possible backfocus, making the camera ideal for off-axis guiding.  In addition, the QHY5III174 uses a more robust LEMO style connector for the guide port.  These connectors are known for being both rugged and reliable.   The QHY5III174 is available in both mono and color versions. The camera is well suited for solar imaging using short focal length telescopes that will capture a full solar disk within the FOV. \u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp

full frame color sensor. The IMX410 is essentially a back-illuminated version of the sensor that used in the Nikon D750 and QHY128C cameras. In addition to BSI, the IMX410 also has larger 5.94 um pixels giving it increases sensitivity of extended objects in low light. The IMX410 is expected to be Sony's most sensitive full frame color sensor for astrophotography.\u003c\/p\u003e\u003ch2 data-animation=\"fadeInUp\"\u003eHigh Full Well Capacity and High Dynamic Range\u003c\/h2\u003e\u003cp\u003eOne benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. When back-illumination is combined with somewhat larger pixels, the full well capacity and cynamic range are improved dramatically. The QHY410C has a full well capacity of 120k electrons! With its low read noise this produces a dynamic range greater than 17,000:1 or more than 14 STOPS. Moreover, the dynamic range remains fairly uniform even at higher gain settings.\u003c\/p\u003e\u003ch2 data-animation=\"fadeInUp\"\u003eLow Read Noise\u003c\/h2\u003e\u003cp\u003eThe QHY410C is capable of only 1.1 electron of read noise at high gain and fast readout speed. One electron of read noise means the camera can achieve a SNR\u0026gt;3 at only 3 to 4 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys and time domain astronomy.\u003c\/p\u003e\u003ch2 data-animation=\"fadeInUp\"\u003eBack-Illuminated\u003c\/h2\u003e\u003cp\u003eSony's Exmor R back-illuminated technology produces sensors that Sony estimates are twice as sensitive as similar front illuminated sensors. QHYCCD tests have borne out this claim. Additionally, Sony sensors are well known for their low dark current. QHYCCD's proprietary thermal noise reduction technology and the QHY40C's dual-stage regulated thermoelectric cooling further reduce dark current to extremely low levels for clean, long duration exposures when required.\u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp data-custom-tab-title\u003eSpecifications\u003c\/p\u003e\n\u003cdiv\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eQHY410C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003eSensor\u003c\/td\u003e\n\u003ctd width=\"116\"\u003eSONY IMX410 Full Frame BSI CMOS Sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003eAR Coating On CMOS chamber\u003c\/td\u003e\n\u003ctd width=\"116\"\u003eYes.

the sensor supplier.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThis sensor is specially designed and manufactured with amateur astronomers in mind who wanted a mono sensor

is 27mm x 21.6mm. Compared to the QHY8L APS-C format of 23.4 x 15.8, the APS-H sensor is significantly larger with over 50% larger image area.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe reason for desiring an APS-H size mono sensor is that there are no other existing mono sensors in size between the KAF-8300 (4\/3inch) and the KAI-11002 (35mm format).\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThis sensor has 16 Megapixels and the APS-H format is suitable for most telescopes, including SCT's that cannot fully illuminate a 35mm frame without some vignetting or distortion at the edges.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eIt is also suitable for commonly available 2inch filters.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe pixel size of this sensor is 6.0um x 6.0um, slightly bigger than the KAF-8300's 5.4um but, due to the larger size of the sensor, it has nearly twice as many pixels as the 8300.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe QE is similar to or higher than 8300 and the 37ke- full well capacity is almost 50% greater than the 8300's 25.5ke-.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eSince the read noise is comparable to the 8300, the dynamic range can be calculated at about 1.5X greater than the 8300.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThis sensor also comes in a color version on request.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\"A\" Series Camera - Fully Integrated:\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003e\u003c\/strong\u003eThe QHY16200A belongs to the new QHYCCD \"A\" series camera family. \"A\" stands for \"ALL-IN-ONE\".\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe camera includes a built-in motor driven filter wheel and natively supports the QHYOAG.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe OAG can be installed on the camera solidly with six screws, consuming a minimum of back focus, precious for some optical systems.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe filter wheels available for the QHY16200A accept 2\" mounted filters, or 50mm unmounted round filters, in carousels with 5 or 7 positions.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe camera is compatible with the medium size QHYOAG.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eIn addition to the filter wheel and OAG, this \"A\" series camera offers an internal USB HUB (2.0) that provides two USB host port and a USB to dual RS232 converter.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eA guiding camera, mount and electric focuser can be connected directly to the camera instead of the computer to reduce cable clutter and the chance of signal loss due to the long cables.

large 6.5µm pixels. Its dual 12-bit A\/D converters enable simultaneous high and low gain acquisition, capturing a massive 56ke- full well depth while achieving read noise as low as 1.7e-. A regulated two-stage TEC cools the sensor to -40°C below ambient, providing the thermal stability required for repeatable scientific measurements, while the USB 3.0 interface transfers full-resolution 8-bit frames at 32.5 FPS.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 4MP GSENSE2020 BSI Sensor: Capturing Photons with 1.7e- Read Noise\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the QHY2020 is a monochrome, back-illuminated GSENSE2020 sensor, optimized for maximum quantum efficiency and minimal noise. With read noise dropping to just 1.7e- in High Gain Channel (HGC) mode, this camera can detect extremely faint signals, making it a powerful tool for applications like spectroscopy, fluorescence imaging, and astronomical photometry. The 2048x2048 array of 6.5µm pixels provides a generous 13.3mm x 13.3mm imaging area, suitable for a wide range of optical systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual 12-bit A\/D: 56ke- Full Well for High Dynamic Range Imaging\u003c\/h3\u003e\n\u003cp\u003eThe QHY2020's standout feature is its dual 12-bit A\/D architecture, which reads out both a high-gain and a low-gain channel for every exposure. This allows you to simultaneously capture faint details near the noise floor and bright structures without saturation. The Low Gain Channel (LGC) mode accesses the sensor's full 56ke- well capacity, preventing blooming on bright stars or saturated sample areas, while the HGC channel ensures faint structures are recorded with the lowest possible read noise.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Speed Capture: 32.5 FPS at Full Frame and 132.3 FPS in ROI\u003c\/h3\u003e\n\u003cp\u003eEngineered for applications where speed is critical, the QHY2020 leverages its USB3.0 interface and a 128MB DDR2 internal buffer to deliver consistent, high-speed data transfer. At full 2048x2048 resolution, the camera can stream 32.5 frames per second in 8-bit mode. For applications like solar imaging, lucky imaging, or adaptive optics, you can define a Region of Interest (ROI) to dramatically increase frame rates, reaching 132.3 FPS for a 480-line window.

The QHY6060's high frame rate and sync ports can help mitigate some of these effects in certain scenarios.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the purpose of the 2GB DDR3 buffer in the QHY6060?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe 2GB DDR3 buffer is a critical component for reliable imaging.

When paired with a GPS timing device like the QHYCCD GPS-BOX, you can achieve highly accurate timestamps for each frame, which is critical for scientific occultation measurements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the benefit of the QHY42's large 11µm pixels for spectroscopy?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eIn spectroscopy, light from a star is spread out into a thin line, meaning each pixel receives very few photons.

amateurs and professionals.  The image area is just over 36mm x 36mm.  It uses an even-illumination mechanical shutter for photometric quality darks and flats.  This shutter is operated by direct drive and has an extraordinarily long life with no other moving parts.    \u003c\/p\u003e\u003cp\u003eThe  KAF−16803 image sensor is a redesigned  version of the popular KAF−16801 image sensor (4096 (H) × 4096 (V) pixel resolution), with enhancements that specifically target the needs of high performance  applications.  Improvements include enhanced quantum efficiency for improved DQE at higher spatial frequencies, lower noise for improved contrast in areas of high density, and anti-blooming protection to prevent image bleed from over exposure in regions outside the area of interest.  The sensor utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode, as well as microlenses to maximize light sensitivity.  When combined with large imaging area and small pixel size, the KAF−16803 provides the sensitivity, resolution and contrast necessary for high quality digital astro-images. \u003c\/p\u003e\u003ch2\u003e\"A\" Series Camera - Fully Integrated\u003c\/h2\u003e\u003cp\u003eThe QHY16803A and QHY09000A belong to the new QHYCCD \"A\" series camera family. \"A\" stands for \"ALL-IN-ONE\".  The cameras include a built-in motor driven filter wheel and natively support the large size QHYOAG.  The OAG can be installed on the camera solidly with six screws, consuming a minimum of back focus, precious for some optical systems.  The built-in filter wheel has 7 positions for 50mm square filters.  The \"A\" series cameras have an internal USB HUB(2.0) that provides two USB host port and a USB to dual RS232 converter.  A guiding camera, mount and electric focuser can be connected directly to the camera instead of the computer to reduce cable clutter and the chance of signal loss due to the long cables. Only a single USB cable is needed to control all the peripherals. \u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp

autoguiding. With a resolution of 1936 x 1216, a peak QE of 77%, and low 3.5e read noise, this camera reliably detects faint guide stars even in sparse star fields. The ASI174MM Mini's 13.4mm sensor diagonal makes it the definitive choice for off-axis guiding with long focal length telescopes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 1\/1.2\" Sensor for Dependable Off-Axis Guiding\u003c\/h3\u003e\n\u003cp\u003eThe primary advantage of the ASI174MM Mini is its expansive 11.34mm x 7.13mm sensor. This provides a significantly larger field of view compared to typical 1\/3\" guide cameras, dramatically increasing the probability of finding a suitable guide star within the pick-off prism of an Off-Axis Guider (OAG). For imagers using Schmidt-Cassegrains or Ritchey-Chrétiens, this larger sensor area is not a luxury—it is the most critical factor for reliable, frustration-free autoguiding.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e5.86µm Pixels for Stable Tracking in Average Seeing\u003c\/h3\u003e\n\u003cp\u003eWhile many cameras pursue smaller pixels for high-resolution planetary imaging, the ASI174MM Mini's larger 5.86µm pixels are optimized for guiding stability. Larger pixels are less susceptible to the rapid, small-scale movements caused by atmospheric turbulence (\"seeing\"), preventing the autoguider from overcorrecting. This results in smoother tracking and rounder stars in your final image, as the camera guides on the star's centroid rather than chasing atmospheric shimmer.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASI174MM Mini vs. ASI120MM-S: A Guiding Comparison\u003c\/h3\u003e\n\u003cp\u003eFor those deciding on a dedicated guide camera, the choice often comes down to the ASI174MM Mini and the popular ASI120MM-S.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eASI120MM-S Advantage:\u003c\/strong\u003e The ASI120MM-S is a proven, highly capable guide camera that is more affordable, making it an excellent starting point for guiding with shorter focal length refractors and guide scopes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASI174MM Mini Advantage:\u003c\/strong\u003e The ASI174MM Mini's 1\/1.2\" sensor physically dwarfs the 1\/3\" sensor in the ASI120MM-S. This translates directly to a wider field and a much higher chance of finding guide stars with an OAG on instruments over 1000mm in focal length.

This design is ideal for short-exposure solar, lunar, and planetary imaging where thermal noise is negligible. However, for multi-minute exposures of faint deep-sky objects, the lack of cooling will result in higher thermal noise compared to a dedicated cooled camera. The small 2.4µm pixels deliver exceptional resolution but require stable seeing and precise focusing to fully exploit their potential, and they pair best with telescopes operating at shorter focal ratios to avoid oversampling.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASI183MC vs. ASI183MM: Color Simplicity vs. Monochrome Sensitivity\u003c\/h3\u003e\n\u003cp\u003eThe primary difference between the ASI183MC and its monochrome sibling, the ASI183MM, is the sensor's Bayer matrix. The ASI183MM offers higher ultimate sensitivity and resolution because it lacks the color filter array, allowing every pixel to capture all incoming light. This makes it the superior choice for advanced imagers using filter wheels for LRGB or narrowband imaging. The ASI183MC, however, provides the significant advantage of one-shot color capture. You get a full-color image in a single exposure, drastically simplifying the acquisition and processing workflow, which is a major benefit for planetary imaging sessions where conditions can change rapidly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the ASI183MC perform on Jupiter with an 8\" f\/10 SCT?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFor planetary imaging, the optimal focal ratio is typically 5 to 7 times the camera's pixel size. With the ASI183MC's 2.4µm pixels, you should aim for a focal ratio between f\/12 and f\/17. On an 8\" f\/10 SCT, you would use a 1.5x or 2x Barlow lens to achieve this ideal image scale, allowing you to resolve fine details in Jupiter's cloud bands under good seeing conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the ZWO ASI183MC for imaging the Orion Nebula (M42)?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, the ASI183MC is sensitive enough to capture bright deep-sky objects like the Orion Nebula (M42) using a series of short exposures (e.g., 30-60 seconds) that can be stacked later. However, as an uncooled camera, it will exhibit more thermal noise on long exposures than a cooled model, which may limit its ability to capture the faintest outer nebulosity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat does \"back-illuminated\" (BSI) mean for the ASI183MC?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eA \u003cstrong\u003eBack-Illuminated Sensor (BSI)\u003c\/strong\u003e places the metal wiring layer below the light-sensitive photodiodes, rather than above them.

Like most color CMOS cameras, the ASI183MC's sensor is sensitive to infrared (IR) light that the human eye cannot see.

nebulae and galaxies with short-focal-length refractors. Its back-illuminated sensor architecture achieves a peak Quantum Efficiency of 84% with readout noise as low as 1.6e, ensuring faint structures are recorded with a high signal-to-noise ratio. A 256MB DDR3 memory buffer ensures stable data transfer at up to 19 fps at full resolution, eliminating dropped frames during critical acquisition sequences.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Resolution Imaging with 2.4µm Pixels\u003c\/h3\u003e\n\u003cp\u003eThe ASI183MC Pro's core strength is its 5496 x 3672 pixel array, which delivers an immense field for framing large targets or cropping into smaller regions without sacrificing detail. The 2.4µm pixel size is an excellent match for wide-field refractors and astrographs under 500mm focal length, achieving high-resolution sampling without excessive barlows or focal extenders. This combination allows you to resolve intricate details in targets like the wispy filaments of the Cygnus Loop (NGC 6960) or the dust lanes in Bode's Galaxy (M81).\u003c\/p\u003e\n\u003cp\u003eThe small pixel size is a trade-off; it demands accurate guiding and good seeing conditions to realize its full potential. When those conditions are met, the level of detail resolved by the ASI183MC Pro rivals that of cameras with much larger, more expensive sensors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e84% QE from a 1\" Back-Illuminated Sensor\u003c\/h3\u003e\n\u003cp\u003eThis camera uses a back-illuminated (BSI) Sony CMOS sensor, which moves the sensor's wiring layer behind the photodiodes instead of in front of them. This design removes obstructions from the light path, dramatically increasing sensitivity and leading to a peak Quantum Efficiency of 84%. You capture a higher percentage of incoming photons, which translates to shorter total integration times to achieve a clean, noise-free image of faint deep-sky objects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eTwo-Stage Cooling and 256MB DDR3 Buffer\u003c\/h3\u003e\n\u003cp\u003eFor long-exposure astrophotography, controlling thermal noise is critical. The ASI183MC Pro uses a two-stage thermoelectric cooler (TEC) that requires a 12V at 3A power source to actively reduce the sensor temperature, significantly lowering dark current noise. This regulated cooling, combined with the integrated anti-dew heater, ensures consistent, low-noise performance across imaging sessions in a wide range of humidity and temperatures from -5°C to 45°C.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable Data Transfer:\u003c\/strong\u003e The onboard 256MB DDR3 buffer acts as a high-speed cache, preventing data loss and frame dropping that can occur when a computer's resources are strained.

short-focal-length instruments. Its back-illuminated design achieves a peak Quantum Efficiency of 84% and maintains low 1.6e read noise, capturing faint signals with high fidelity. At full resolution, the camera delivers 19 frames per second over its USB 3.0 interface, providing the speed needed for high-resolution lunar, solar, and planetary imaging.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Resolution Sampling with 2.4µm Pixels\u003c\/h3\u003e\n\u003cp\u003eThe ASI183MM's 2.4µm pixels are perfectly suited for modern, short focal length refractors and imaging Newtonians. This combination allows you to achieve high-resolution image sampling without needing a Barlow lens, capturing fine details in nebulae and galaxies.

This architecture maximizes light collection, pushing the peak Quantum Efficiency to 84% and enabling over 60% sensitivity in the critical Hydrogen-alpha line. As an uncooled camera, the ASI183MM excels at shorter exposures for lucky imaging and narrowband work, though thermal noise will become a factor on multi-minute exposures of faint deep-sky objects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASI183MM vs. ASI183MC: The Monochrome Advantage at 20.2 MP\u003c\/h3\u003e\n\u003cp\u003eWhile its color counterpart, the ASI183MC, simplifies imaging with one-shot-color convenience, the ASI183MM Mono holds a distinct advantage in sensitivity and resolution.

Its small 2.4µm pixels are engineered to resolve fine details in nebulae and galaxies when paired with short-focal-length refractors and imaging astrographs. A peak Quantum Efficiency of 84% and exceptionally low 1.6e read noise allow you to capture faint signal even in short exposures. The two-stage TEC cooler and internal buffer work together to deliver clean, low-noise frames at up to 19 fps at full resolution.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e20.2 MP Resolution from a 1\" BSI Sensor\u003c\/h3\u003e\n\u003cp\u003eThe core of the ASI183MM Pro is its 5496 x 3672 pixel back-illuminated CMOS sensor. The 2.4µm pixel size creates an ideal pairing with wide-field refractors, allowing you to sample the sky at a high resolution without needing extreme focal lengths. The primary trade-off with such small pixels is their sensitivity to seeing conditions; they perform best under steady skies and demand precise focus to leverage their full resolving power.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSignal Capture at 84% Peak QE and 1.6e Read Noise\u003c\/h3\u003e\n\u003cp\u003eThis camera's back-illuminated sensor architecture achieves a peak Quantum Efficiency of 84%, capturing a high percentage of incoming photons.

The ASI183MM Pro's cooler can lower the sensor temperature to more than 35°C below ambient. To ensure error-free data transfer, especially at high frame rates over USB 3.0, the camera includes a 256MB DDR3 memory buffer.

The back-illuminated (BSI) architecture maximizes photon collection, while the large 4.63µm pixels are well-suited to a wide range of refractors and reflectors. Its greatest asset is the 63.7ke- full well depth, which allows you to take longer sub-exposures on targets with bright stars, like the Orion Nebula (M42) or the Hercules Cluster (M13), without saturating the stars and losing color information.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eTwo-Stage Cooling and 256MB DDR3 Buffer\u003c\/h3\u003e\n\u003cp\u003eDeep-sky astrophotography requires long exposures, where thermal noise from the sensor can degrade image quality. The ASI294MC Pro's two-stage TEC cooling system dramatically lowers sensor temperature, resulting in clean, low-noise images. A built-in anti-dew heater on the protective window prevents moisture from forming during humid nights. For data stability, the 256MB DDR3 memory buffer acts as a high-speed cache, preventing dropped frames that can occur with slower computers or heavy USB traffic, a critical feature when capturing hundreds of exposures for a final image.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASI294MC Pro vs. ASI533MC Pro: 4\/3\" vs. 1\" Sensor\u003c\/h3\u003e\n\u003cp\u003eWhile the ASI533MC Pro offers the benefit of zero amp glow, the ASI294MC Pro provides a significantly larger imaging canvas.

The camera’s firmware is constantly monitoring the sensor and heat sink temperatures, as well as controlling the cooler power.  When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling.  When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.\u003c\/p\u003e\n\u003ch3\u003eAdvanced Software Included\u003c\/h3\u003e\n\u003cp\u003eAll SBIG cameras come with our MaxIm LT software – a $200 value!

This is quite a feat considering the Aluma’s very compact and lightweight package.\u003c\/p\u003e\n\u003cp\u003eSmartCooling automatically adjusts the fan speed to optimize cooler performance and power consumption.  The camera’s firmware is constantly monitoring the sensor and heat sink temperatures, as well as controlling the cooler power.  When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling.  When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.\u003c\/p\u003e\n\u003ch3\u003eAdvanced Software Included\u003c\/h3\u003e\n\u003cp\u003eAll SBIG cameras come with our MaxIm LT software – a $200 value!

This allows the AO-8A to not only remove the effects of periodic error, drift, and wind gusts, but also reduce the effects of atmospheric seeing.\u003c\/p\u003e\n\u003cp\u003eFor more information please see \u003ca href=\"https:\/\/diffractionlimited.com\/product\/ao-8t\/\"\u003eAO-8T\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv data-custom-tab=\"\"\u003e\n\u003cp data-custom-tab-title=\"\"\u003eSpecifications\u003c\/p\u003e\n\u003cdiv\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eOAG Option\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eStarChaser\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePeak QE\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e93%\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAntiblooming\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003en\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor Size\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e13.3 mm x 13.3 mm\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePixel Size\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e13 μm\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal Pixels\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e1 million pixels\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSelf-Guiding In Front of Filters\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003ey\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImaging \/ Pixel Array\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e1056 x 1027\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImaging Sensor\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eE2V CCD47-10 AIMO\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFull Well Capacity\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e100,000 e-\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFilter Wheel Option\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003ey\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShutter\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eMechanical, Even-illumination\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e12 VDC, 5A max\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRemote Guide Head\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003ey\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAdaptive Optics Option\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eY\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePixel Digitization Rate\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e1 MPix\/sec\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOS Compatibility\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eWindows 7, 8, 10 x86\/x64, MacOS 10.14 \"Mojave\" x86 binaries, Ubuntu 18.04 LTS x64, Raspbian Buster armhf, Ubuntu MATE arm64\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComputer Interface\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eUSB 2.0, USB 2.0 \/ WiFi 802.11 b\/g\/n\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExposure\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e0.1 sec minimum\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCooling Delta\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e~ 50 °C\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRead Noise\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e5 e- typical\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eA\/D Converter\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e16 bits\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e2.2 lbs\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFilter Size\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e36mm \/ 1.25\"\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFull Frame Download\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003e~1 sec via USB or WiFi\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature Regulation\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003ey\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003eMidband, Broadband, Enhanced UV\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDark Current e\/p\/s at 0 C\u003c\/th\u003e\n\u003ctd\u003e\u003cp\u003etypical 20 e-\/pix\/sec;

This is quite a feat considering the Aluma CCD’s very compact and lightweight package.\u003c\/p\u003e\u003cp\u003eSmartCooling automatically adjusts the fan speed to optimize cooler performance and power consumption.  The camera’s firmware is constantly monitoring the sensor and heat sink temperatures, as well as controlling the cooler power.  When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling.  When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.\u003c\/p\u003e\u003ch3\u003eAdvanced Software Included\u003c\/h3\u003e\u003cp\u003eAll Aluma CCD cameras come with our MaxIm LT software – a $200 value!

The camera’s advanced design permits high speed download via the USB 3.0 connection to the control computer. The Aluma AC4040 uses the Gpixel GSENSE4040 CMOS sensor with 16.8 million pixels at 9 microns. The sensor measures almost 37mm square. The Aluma AC series has powerful two stage cooling and supports optional water cooling.

This means the overall sensitivity of the Aluma AC4040 is much higher than its CCD predecessor.  The FSI camera is available with an economical Grade 2 sensor, or a premium Grade 1 sensor with fewer pixel defects.\u003c\/p\u003e\n\u003cp\u003eFor the most demanding applications, the Aluma AC4040BSI features a windowless Back-Side Illuminated (BSI) sensor, which has an incredible peak QE of 95%.

At the same time, the modern CMOS sensors have much lower read noise than the equivalent CCD.

This does however result in a lot of extra disk usage and post-processing.\u003c\/p\u003e\n\u003cp\u003eStackPro™ performs the stacking automatically, inside the camera.  It automatically subdivides your exposure into up to 16 individual subexposures, and stacks them inside the camera prior to download.

It produces extremely clean images with few hot pixels.\u003c\/p\u003e\n\u003cp\u003eDue to the extremely low read noise and fast readout, the STC-7 is best used with shorter sub-exposures than for comparable CCD cameras.  A typical sub-exposure will be only 30-60 seconds, versus 5-10 minutes, while still achieving the same or better noise performance and overall dynamic range after stacking.  This has many advantages including the ability to take unguided exposures without trailing.  It can also be used for lunar and planetary imaging at high resolution, given its high sensitivity, wide exposure range, and fast readout.\u003c\/p\u003e\n\u003cp\u003eThe STC-7 is optimal for telescopes having a focal length of 1000 to 1500 mm.

Its default 11.7 MP mode uses 4.63µm pixels to achieve a massive 66.4k full well capacity, while an unlockable mode reconfigures the sensor to 47 MP with 2.3µm pixels for maximum detail on smaller targets.

In its standard Bin2 mode, the 4.63µm pixels and 14-bit ADC are optimized for capturing targets with a vast brightness range, like the Orion Nebula (M42), without saturating the core. For smaller targets like the Whirlpool Galaxy (M51) or planetary nebulae, you can switch to the unlocked Bin1 mode. This mode uses the sensor's native 2.3µm pixels for a 47 MP final image, resolving finer details at the trade-off of a lower 14k full well and 12-bit ADC output.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e90% QE and 1.2e Read Noise at -40°C\u003c\/h3\u003e\n\u003cp\u003eDeep-sky imaging relies on capturing every possible photon while introducing minimal noise, and the ASI294MM Pro is engineered for exactly that. The back-illuminated sensor architecture achieves a peak quantum efficiency of ~90%, ensuring the vast majority of incoming light is converted to signal. To keep noise under control during long exposures, the two-stage TEC cooler drops the sensor temperature by up to 40°C below ambient, while the camera's electronics produce a minimum read noise of only 1.2 electrons. This combination keeps the faint, outer structures of galaxies well above the noise floor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASI294MM Pro vs. ASI294MC Pro: Monochrome Sensitivity\u003c\/h3\u003e\n\u003cp\u003eWhile the color ASI294MC Pro offers the simplicity of single-shot imaging, the ASI294MM Pro provides the raw sensitivity needed for advanced astrophotography. By removing the Bayer filter matrix found on the color sensor, the monochrome version achieves a higher peak QE of ~90% and captures the full resolution of the sensor for every filtered exposure. This makes it the definitive choice for narrowband imaging with Ha, SII, and OIII filters, allowing you to isolate specific nebula emissions with maximum signal strength—something a color camera cannot do with the same efficiency.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e256MB DDR3 Buffer and 16.5 FPS Data Transfer\u003c\/h3\u003e\n\u003cp\u003eTo ensure stable, drop-free imaging sessions, ZWO includes a 256MB DDR3 memory buffer.

Camera\u003c\/h2\u003e\n\u003cp\u003eThe ZWO ASI294MM combines a large 4\/3\" format Sony sensor with deep 66ke- full well capacity and ~90% peak quantum efficiency to deliver exceptional signal-to-noise performance for solar system imaging. Its 11.7 MP resolution captures expansive lunar mosaics and full-disc solar images, while the extremely low 1.26e- read noise ensures that faint planetary details are not lost in the background. At full 4144 x 2822 resolution, the camera transmits data at up to 19 FPS over its USB 3.0 interface, fast enough for lucky imaging during moments of steady seeing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSony IMX492 Sensor: ~90% QE and 1.26e- Read Noise\u003c\/h3\u003e\n\u003cp\u003eThe core of the ASI294MM is its back-illuminated Sony CMOS sensor, which achieves a peak quantum efficiency of approximately 90%. This extreme sensitivity means the camera captures nearly every photon that hits it, allowing you to use shorter exposures to freeze atmospheric turbulence. Paired with a readout noise floor as low as 1.26e-, the sensor maintains a high dynamic range, preserving subtle tonal variations in Jupiter's cloud bands and delicate structures in solar prominences.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSoftware-Unlocked Bin 1 Mode for 47MP Resolution\u003c\/h3\u003e\n\u003cp\u003eA unique feature of the ASI294MM is a software-selectable mode that unlocks the sensor's native resolution. In this mode, the camera operates with smaller effective pixels and a resolution of 47 megapixels. This provides a significant increase in image scale without changing your optical train, allowing you to resolve finer details on planetary surfaces. This mode is a powerful tool for imagers seeking the highest possible resolution when seeing conditions permit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eASI294MM Mono vs. One-Shot-Color Alternatives\u003c\/h3\u003e\n\u003cp\u003eThe primary advantage of the ASI294MM's monochrome sensor is its raw sensitivity. By removing the Bayer color filter array found on color cameras, it captures 100% of the incoming light at every pixel, avoiding the significant light loss inherent to color filter matrices. This translates directly to stronger signal and cleaner data per frame.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonochrome Advantage:\u003c\/strong\u003e Capturing in monochrome with separate LRGB filters consistently produces sharper, more detailed final images than a one-shot-color camera with the same sensor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-Shot-Color Advantage:\u003c\/strong\u003e A color camera offers a much simpler workflow, capturing a full-color image in a single set of exposures without the need for a filter wheel.

This makes it a specialist for lunar, solar, and planetary work where thousands of frames are captured in minutes. For long-exposure deep-sky imaging of faint nebulae, where thermal noise from the sensor becomes a limiting factor, a cooled camera is the recommended tool.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e19 FPS Data Transfer with USB 3.0 and ST-4 Guiding\u003c\/h3\u003e\n\u003cp\u003eTo handle the massive amount of data generated by the 11.7 MP sensor, the ASI294MM uses a USB 3.0 interface capable of sustaining a full-resolution frame rate of 19 FPS. This ensures you never miss a moment of stable seeing. The camera also includes a standard ST-4 guide port, allowing its high sensitivity to be used for autoguiding on faint stars when not being used as a primary imager.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main advantage of the ZWO ASI294MM's 4\/3\" sensor?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe large 4\/3\" sensor, with a 23.2mm diagonal, provides a much wider field of view than smaller planetary cameras.

The native 16-bit A\/D conversion provides 65,536 levels of gray, compared to the 4,096 levels of a 12-bit camera. This results in dramatically smoother gradients in nebulae and more accurate stellar photometry, eliminating the \"posterization\" or banding that can appear in heavily stretched images from less capable sensors. Combined with its full-frame size and BSI sensitivity, the QHY600C delivers a level of image depth and quality previously reserved for high-end CCDs, but with all the advantages of modern CMOS technology.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the benefit of the QHY600C's 2GB DDR3 buffer?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eThe \u003cstrong\u003e2GB DDR3 buffer\u003c\/strong\u003e acts as a high-speed temporary memory cache for the massive 61.17MP images before they are sent to your computer.
