Its 26-megapixel array (6252×4176, 3.76 µm pixels) spans a 23.5 mm×15.7 mm frame with a 28.3 mm diagonal, digitised at a true 16-bit. Two-stage TEC cooling holds the sensor about 40 °C below ambient, and a large 71.7k e− full well gives it the dynamic range for demanding deep-sky work without changing filters.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you shoot deep-sky astrophotography and want a large, high-resolution colour sensor in a single, cooled package — broadband galaxies and nebulae, wide star fields, and colour narrowband through a dual\/tri-band filter. The APS-C format and 3.76 µm pixels pair well with refractors and mid-focal-length reflectors.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSony IMX571 APS-C CMOS (color):\u003c\/strong\u003e 26 MP across a 23.5×15.7 mm frame for wide, detailed fields.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e16-bit ADC:\u003c\/strong\u003e fine tonal gradation across the 71.7k e− full well.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-stage TEC cooling:\u003c\/strong\u003e regulated to 40 °C ±2 °C below ambient, dropping dark current to 0.000105 e\/s\/pix at −20 °C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow read noise:\u003c\/strong\u003e 3.9 e− down to 1.0 e− depending on gain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e512 MB DDR3 buffer over Type-C USB3.0:\u003c\/strong\u003e a stable data path for large 26 MP frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAR-coated window and tilt plate:\u003c\/strong\u003e D46×2 mm multi-layer AR glass with an adjustable sensor tilt plate.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe IMX571 is an APS-C back-illuminated colour CMOS with a RGGB Bayer matrix, 3.76 µm pixels, 71.7k e− full well and read noise from 3.9 e− to 1.0 e−, digitised at 16-bit with a peak QE near 80%. At full 26 MP resolution the camera runs about 10 fps (10-bit) over USB3.0. Sensor-to-flange backfocus is 17.5 mm with the tilt plate installed (12.5 mm without it), a figure to carry through the imaging train. Two-stage thermoelectric cooling regulates the sensor to 40 °C ±2 °C below ambient. The 90 mm body offers M48×0.75, 2\" and 1.25\" interfaces.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroadband deep-sky:\u003c\/strong\u003e galaxies, star clusters and reflection nebulae in one-shot colour.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNarrowband colour:\u003c\/strong\u003e emission nebulae through dual- or tri-band filters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide-field imaging:\u003c\/strong\u003e the APS-C frame frames large targets and mosaic panels efficiently.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe camera provides M48×0.75, 2\" and 1.25\" connections and needs 17.5 mm of backfocus with the tilt plate fitted — the standard 55 mm imaging-train figure is reached by adding a filter drawer or spacer set to the flattener\/reducer. Data runs over Type-C USB3.0. The TEC draws up to 3 A, so a 12 V DC supply rated to at least 5 A powers the cooling. As a one-shot-color camera it needs no filter wheel for RGB, though a light-pollution or dual-band filter is common from suburban skies.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling needs its own 12 V supply:\u003c\/strong\u003e a 5 A (or higher) adapter runs the TEC; USB carries data only.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackfocus is 17.5 mm with the tilt plate:\u003c\/strong\u003e plan spacers so the total train reaches your flattener's specified distance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-shot color:\u003c\/strong\u003e convenient for RGB in a single exposure; a dual-band filter helps under light pollution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublished weight is 650 g:\u003c\/strong\u003e a factor in focuser and mount balance once the filter drawer and adapters are attached.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs it difficult to set up?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. It threads to a flattener or field-flattener train through its M48\/2\" interface, connects over USB-C, and adds one step over an uncooled camera — a 12 V, 5 A supply for the cooler.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is it best used for?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCooled, one-shot-color deep-sky astrophotography across an APS-C field.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a filter wheel?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNot for colour — the Bayer sensor captures RGB directly.
