The IMX294 is a 4\/3″ sensor (19.2 mm × 13 mm, 23.2 mm diagonal) with 4.63 µm pixels — a large, sensitive pixel that gathers light quickly for its size. Its native full-well capacity is 65.8 ke-, read noise drops from 7.8e- to 1.2e- with gain, and a High Conversion Gain (HCG) mode keeps noise low. A two-stage TEC cools the sensor 40°C ± 2°C below ambient for long, clean deep-sky exposures.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis is a good match if you shoot wide-field deep-sky targets in one-shot color — large nebulae, star fields, and extended objects that suit a 4\/3″ frame. The larger 4.63 µm pixels pair well with short-to-medium focal length refractors, and the cooling makes it capable on faint subjects under long exposure.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSony IMX294 4\/3″ color sensor:\u003c\/strong\u003e 4144 × 2824 resolution with light-hungry 4.63 µm pixels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e65.8 ke- full well, 14-bit ADC:\u003c\/strong\u003e broad dynamic range for stars and nebulosity in the same frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRead noise down to 1.2e- with HCG:\u003c\/strong\u003e low-noise capture at high gain for faint targets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-stage TEC, 40°C ± 2°C below ambient:\u003c\/strong\u003e strong cooling for low dark current.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM48, 2″, and 1.25″ interfaces:\u003c\/strong\u003e flexible connection to a range of imaging trains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e512 MB DDR3 buffer:\u003c\/strong\u003e steadies the USB3.0 data stream.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe IMX294's 4.63 µm pixels are large for a modern CMOS, which gives high sensitivity and a generous full well relative to pixel count — well suited to wide-field color imaging. Peak quantum efficiency is about 76%, and the HCG mode combined with 14-bit sampling preserves dynamic range while lowering read noise at high gain. Cooling to 40°C ± 2°C below ambient controls thermal noise across long integrations.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/Artemis-C-QE3_c48b040b-338b-4e4e-b094-0992b2c43ec6.png?v=1784235837\" alt=\"Player One Astronomy Artemis-C Pro IMX294 color quantum efficiency QE curve for deep-sky imaging\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide-field deep-sky color:\u003c\/strong\u003e large nebulae and star fields on short-to-medium focal lengths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooled long-exposure imaging:\u003c\/strong\u003e faint targets from suburban or dark skies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-band and light-pollution filtered work:\u003c\/strong\u003e the large sensor pairs well with 2″ filters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCompatibility \u0026amp; Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Artemis-C Pro connects over USB3.0\/USB2.0 (Type-C) and powers its cooler from a 12 V DC 5.5 × 2.1 mm input.
