The IMX571 spans a 28.3 mm diagonal (23.5 mm × 15.7 mm, 6252 × 4176 pixels) with 3.76 µm pixels, a deep 71.7 ke- full-well capacity, and a true 16-bit ADC. Read noise falls to about 1.0e-, and a two-stage TEC cools the sensor 40°C ± 2°C below ambient. Peak quantum efficiency is about 91% — a high-performance mono sensor for serious deep-sky work.\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 image deep-sky objects in narrowband or LRGB and want the larger APS-C field and 16-bit depth for demanding projects. The generous full well and low read noise suit both bright galaxy cores and faint nebulosity, and the APS-C frame captures wide targets at moderate focal lengths.\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 IMX571 APS-C mono sensor:\u003c\/strong\u003e 26 MP at 6252 × 4176 with 3.76 µm pixels across a 28.3 mm diagonal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e16-bit ADC, 71.7 ke- full well:\u003c\/strong\u003e wide dynamic range and fine tonal gradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRead noise about 1.0e-:\u003c\/strong\u003e a very low floor for faint narrowband signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak QE about 91%:\u003c\/strong\u003e high mono sensitivity across the spectrum.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-stage TEC, 40°C ± 2°C below ambient:\u003c\/strong\u003e strong cooling for long integrations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM48, 2″, and 1.25″ interfaces:\u003c\/strong\u003e flexible connection for filter wheels and flatteners.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe IMX571 is a back-illuminated APS-C sensor whose 3.76 µm pixels balance resolution and well depth across a large 28.3 mm diagonal. The 16-bit ADC and 71.7 ke- full well give the dynamic range to hold bright stars while stacking faint detail, and a peak QE near 91% makes it efficient in narrowband. Cooling to 40°C ± 2°C below ambient keeps dark current low across the long sub-exposures this sensor is built for.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/IMX571-monochrome-QE-1024x542_71862afa-9df6-4d27-ada3-a4a84dc63c27.png?v=1784235854\" alt=\"Player One Astronomy Poseidon-M Pro IMX571 monochrome quantum efficiency QE curve for narrowband 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\u003eNarrowband nebula imaging:\u003c\/strong\u003e high-contrast H-alpha, OIII, and SII across an APS-C field.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLRGB deep-sky work:\u003c\/strong\u003e galaxies, clusters, and large nebulae at moderate focal lengths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooled long-exposure projects:\u003c\/strong\u003e faint targets that reward low read noise and deep wells.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCompatibility \u0026amp; Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Poseidon-M Pro connects over USB3.0\/USB2.0 (Type-C) and powers its cooler from a 12 V DC input.
