In fact, you can get the “SBFL (shorter back focal length)” version of 268C right now. The previous 268c has a back focal length of 17.5mm, and since it cannot connect to the scope without CAA, so it’s actual BFL is 17.5mm+6mm=23.5mm. Now after the change, 268C’s BFL will be shorten to 14.5mm, which provides more spaces for a filter wheel drawer, or an eletric CAA, or DSLR Lens, etc.\u003c\/p\u003e\n\u003cp\u003eWith the advantage of low readout noise and high-speed readout, CMOS technology has revolutionized astronomical imaging.  A monochrome, back-illuminated, high-sensitivity, astronomical imaging camera is the ideal choice for astro-imagers.\u003c\/p\u003e\n\u003cp\u003eThe QHY268M\/C is a new generation of back-illuminated CMOS cameras with true 16-bit A\/D and 3.76um pixels.  This new Sony sensor is an ideal CMOS sensor exhibiting no amplifer glow. 16-bit A\/D gives high resolution sampling of the whole full well range.  Digitizing 0-65535 levels yields a smooth image with continuous gradation of greyscale levels.

The pixel count of the latest generation of CMOS sensors is very high resulting in greater memory requirements for temporary and permanent storage.  The QHY268 has adopted a large-capacity memory of up to 1GB.  Data throughput is doubled. This large image buffer meets the needs of high-speed image acquisition and transmission of the new generation of CMOS, making shooting of multiple frames smoother and less stuttered, further reducing the pressure on the computer CPU.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003e\u003cstrong\u003eUSB Re-connection by 12V Power on\/off\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe 268 camera’s USB interface to the computer can be connected or disconnected by turning on and off the camera’s 12V power, without the need to plug and unplug the USB cable.

This is particularly helpful for sensors with small pixels.In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.\u003c\/p\u003e\n\u003cp\u003eIn the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.\u003c\/p\u003e\n\u003ch4\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h4\u003e\n\u003ch4\u003e\u003cstrong\u003eZero Amplify Glow\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThis is also a zero amplifer glow camera.\u003c\/p\u003e\n\u003ch4\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003ch4\u003e\n\u003ca class=\"oceanwp-lightbox\" href=\"https:\/\/www.qhyccd.com\/wp-content\/uploads\/20210602542.png\"\u003e\u003c\/a\u003e\u003cstrong\u003eTRUE RAW Data\u003c\/strong\u003e\n\u003c\/h4\u003e\n\u003cp\u003eIn the DSLR implementation there is a RAW image output, but typically it is not completely RAW.  Some evidence of noise reduction and hot pixel removal is still visible on close inspection.  This can have a negative effect on the image for astronomy such as the “star eater” effect.  However,  QHY Cameras offer TRUE RAW IMAGE OUTPUT and produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.\u003c\/p\u003e\n\u003ch4\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h4\u003e\n\u003ch4\u003e\u003cstrong\u003eAnti-Dew Technology\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eBased on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions.
