The sensor's on-chip FPN (Fixed Pattern Noise) calibration function solves one of the major problems of CMOS technology, resulting in images that are clear and uniform, even under high gain. With these advantages, the QHY5L-II provides outstanding image quality for planetary imaging, autoguiding, deep-sky and all-sky imaging. Available in both color and monochrome versions.  The sensor has 1280 x 960 pixels at 3.75um and the camera is capable of 30 frames per second in high resolution mode, 106 FPS in VGA mode.  \u003c\/span\u003e\u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp data-custom-tab-title\u003eSpecifications\u003c\/p\u003e\n\u003cdiv\u003e\u003ctable border=\"0\" width=\"174\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n\u003ccolgroup\u003e\u003ccol span=\"2\" width=\"87\"\u003e\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"87\" height=\"21\"\u003eSensor\u003c\/td\u003e\n\u003ctd width=\"87\"\u003eMT9M034\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eTotal Pixels\u003c\/td\u003e\n\u003ctd\u003e1.2 Megapixels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003ePixel Size\u003c\/td\u003e\n\u003ctd\u003e3.75um\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003ePixel Array\u003c\/td\u003e\n\u003ctd\u003e1280 x 960\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eOptical Format\u003c\/td\u003e\n\u003ctd\u003e1\/3 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eFPS @ 640 x 480\u003c\/td\u003e\n\u003ctd\u003e106\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eFPS @ Full Resolution\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003ePeak QE\u003c\/td\u003e\n\u003ctd\u003e0.74\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eA\/D Resolution\u003c\/td\u003e\n\u003ctd\u003e12-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eShutter\u003c\/td\u003e\n\u003ctd\u003eElectronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eDynamic Range\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;115 dB HDR Mode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"21\"\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eColor 45g,  Mono 43g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003cdiv data-custom-tab\u003e\n\u003cp data-custom-tab-title\u003eIn the Box\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/t\/6\/assets\/description_image_QHYCCD_QHY5L_II_In_the_Box.jpeg?v=1684338349\" alt=\"QHYCCD QHY5-II-M In the Box\"\u003e\u003cdiv\u003eNote: The spacer is used to set the back focus of the CS\/C lens to correct value.

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.

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

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.
