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.

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

range 11.7 MP mode and a high-resolution 46.8 MP mode. In its standard configuration, the 4.63µm pixels and deep 65ke- full well capacity capture faint nebulosity and bright star cores without saturation. For detailed targets, the extended mode unlocks the sensor's native resolution, while the dual-gain system drives read noise down to an exceptionally low 1.2e- for clean, smooth backgrounds.\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 4\/3-inch Sensor with 11.7 MP and 46.8 MP Modes\u003c\/h3\u003e\n\u003cp\u003eThe core of the QHY294M-Pro is its adaptable Sony IMX492 back-illuminated sensor. In its default 11.7 MP mode, the sensor provides large 4.63µm pixels, ideal for collecting maximum light on deep-sky objects and pairing well with a wide range of telescope focal lengths. This mode also boasts a massive 65ke- full well capacity, preserving star color in dense fields and capturing subtle details in bright galactic cores.\u003c\/p\u003e\n\u003cp\u003eWhen you need maximum resolution for smaller galaxies or lunar and solar imaging, you can switch to the extended 46.8 MP mode. This unlocks the sensor's native pixel array, providing the resolving power needed for highly detailed targets. This dual-mode capability allows the QHY294M-Pro to act as both a sensitive deep-sky camera and a high-resolution planetary imager, all in a single 650g body.\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 Gain Architecture: 1.2e- Read Noise for Faint Targets\u003c\/h3\u003e\n\u003cp\u003eThe QHY294M-Pro incorporates a dual gain system that automatically optimizes performance based on your gain setting. For bright objects or broadband imaging, the Low Gain Mode (LGC) prioritizes a high full well capacity. When the gain is set to 1600, the camera switches into High Gain Mode (HGC), dramatically dropping the read noise to a mere 1.2e- to 1.6e-.\u003c\/p\u003e\n\u003cp\u003eThis ultra-low read noise is a significant advantage for narrowband imaging, where signals can be extremely faint. By keeping electronics noise below the skyglow background, the HGC mode ensures that the faintest wisps of nebulosity in targets like the Cygnus Loop (NGC 6960) are captured with exceptional clarity and contrast.\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\u003e-35°C Cooling \u0026amp; 256MB DDR3 Buffer for Clean, Stable Data\u003c\/h3\u003e\n\u003cp\u003eConsistent, repeatable data is critical for astrophotography, and the QHY294M-Pro is engineered for stability.

To prevent data transmission bottlenecks that can cause dropped frames, the QHY600C incorporates a 2GB DDR3 image buffer. This buffer ensures a smooth, consistent data stream to your computer over the USB 3.0 interface, even if the host PC is under heavy load. You can confidently capture full-resolution 16-bit frames at up to 2.5 FPS without interruption, which is essential for techniques like lucky imaging on smaller deep-sky objects or creating detailed mosaics.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003e-35°C Regulated Cooling with Integrated M54\/M48 Interface\u003c\/h3\u003e\n      \u003cp\u003eThermal noise is the enemy of long-exposure astrophotography.

Camera\u003c\/h2\u003e\n\u003cp\u003eThe QHY600C PRO SBFL combines a full-frame 61.17 megapixel Sony IMX455 BSI sensor with a native 16-bit A\/D converter, delivering an unprecedented level of resolution and dynamic range for scientific imaging. With multiple readout modes offering noise as low as 1.1e- and a full well capacity exceeding 80ke-, this camera captures both the faintest nebulosity and brightest stellar cores in a single exposure. Data integrity is ensured by a 2GB DDR3 buffer and dual 2x10Gigabit Fiber interfaces, enabling a full-resolution 16-bit frame rate of up to 3.5 FPS for demanding research applications.\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\u003eFull-Frame 61.17MP Sony IMX455 Sensor: Native 16-Bit Depth\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the QHY600C Pro is the 36mm x 24mm Sony IMX455 sensor, which provides an enormous 9576 x 6388 pixel array. The 3.76µm pixels are an ideal match for high-resolution refractors and corrected reflectors, sampling the sky with immense detail. Unlike cameras that use 12-bit or 14-bit conversion, the QHY600 Pro employs a true, native 16-bit A\/D converter, rendering 65,535 distinct grayscale levels for exceptionally smooth tonal gradations in 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\u003eMulti-Mode Readout: 1.1e- Read Noise and \u0026gt;80ke- Full Well\u003c\/h3\u003e\n\u003cp\u003eThe QHY600C Pro offers several selectable readout modes to optimize the camera for any target. In High Gain Mode, read noise plummets to a mere 1.1e-, allowing you to extract faint signal from photon-starved regions with minimal noise penalty. For bright targets or long-exposure narrowband imaging, the Extended Full Well Mode expands pixel capacity to over 80ke-, preventing saturated stars and preserving highlight detail. This flexibility, combined with a dark current of just 0.0022e-\/pixel\/sec at -20°C and zero amplifier glow, ensures a clean, data-rich foundation for your images.\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\u003eProfessional I\/O: 2x10Gbit Fiber, USB3.0, and a 2GB DDR3 Buffer\u003c\/h3\u003e\n\u003cp\u003eDesigned for applications where speed and reliability are critical, the QHY600C Pro includes both a standard USB3.0 port and a dual 10Gigabit Fiber Optic interface.

Camera\u003c\/h2\u003e\n\u003cp\u003eThe QHY1920 scientific camera is engineered for low-light applications, combining a 2.3 Megapixel BSI sensor with massive 12µm pixels on a 23mm x 14.4mm imaging area. With a deep 51ke- full well capacity, 12-bit A\/D conversion, and read noise as low as 0.74e-, it captures faint signals with high dynamic range. The camera maintains a consistent 58 FPS over its USB3.0 interface, supported by a 128MB DDR2 memory buffer to prevent dropped frames during high-speed acquisition.\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\u003eLow-Light Sensitivity: 12µm Pixels and 0.74e- Read Noise\u003c\/h3\u003e\n\u003cp\u003eThe QHY1920's primary strength is its exceptional sensitivity. The 12µm pixels provide a massive surface area for photon collection, a critical advantage for photon-starved applications like spectroscopy or capturing faint near-infrared (NIR) sources. This is paired with a Back-Side Illuminated (BSI) sensor architecture and read noise as low as 0.74e-, ensuring that the weakest signals are not lost in camera electronics.\u003c\/p\u003e\n\u003cp\u003eWhile the 2.3 Megapixel resolution is modest, the trade-off is for raw light-gathering power.
