The IMX455 is a 35 mm full-frame sensor (43.3 mm diagonal, 36 mm × 24 mm, 9576 × 6388 pixels) with 3.76 µm pixels, a 71.6 ke- full well, and a true 16-bit ADC. A two-stage TEC cools it 35°C ± 2°C below ambient, and an integrated adjustable anti-dew heater keeps the optical window clear. This is a large-format camera for wide, high-resolution deep-sky imaging.\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 wide deep-sky fields at high resolution and want the reach of a full-frame sensor in one-shot color. The 61 MP resolution and 43.3 mm diagonal capture expansive nebulae, large galaxies, and mosaic-scale fields, paired with an imaging refractor or astrograph that covers the full-frame circle.\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 IMX455 full-frame color sensor:\u003c\/strong\u003e 61 MP at 9576 × 6388 across a 43.3 mm diagonal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e16-bit ADC, 71.6 ke- full well:\u003c\/strong\u003e wide dynamic range and smooth tonal depth for demanding data.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRead noise down to 1.27e-:\u003c\/strong\u003e a low floor for faint signal on long exposures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-stage TEC, 35°C ± 2°C below ambient:\u003c\/strong\u003e controls dark current across the large sensor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated anti-dew heater:\u003c\/strong\u003e adjustable power keeps the window clear in humid conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM54 and 2″ interfaces:\u003c\/strong\u003e larger thread to illuminate the full-frame circle without vignetting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe IMX455 is a back-illuminated full-frame sensor whose 3.76 µm pixels give 61 MP resolution across a 36 mm × 24 mm area. The 16-bit ADC finely samples the 71.6 ke- full well for wide dynamic range, and peak QE is about 80% for a color device. Cooling to 35°C ± 2°C below ambient plus the adjustable anti-dew heater keep noise and condensation in check, and a D55 × 2 mm AR Plus multi-layer coated window covers the large sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/Zeus455C-QE_857f538c-526d-4080-971b-d82b190fe58e.png?v=1784235871\" alt=\"Player One Astronomy ZEUS 455C Pro IMX455 color quantum efficiency QE curve for full-frame 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 full-frame color:\u003c\/strong\u003e large nebulae, galaxies, and expansive star fields.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-resolution single-frame imaging:\u003c\/strong\u003e 61 MP detail that reduces the need for mosaics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooled long-exposure deep-sky:\u003c\/strong\u003e faint targets with low thermal noise.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCompatibility \u0026amp; Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe ZEUS 455C Pro connects over USB3.0\/USB2.0 (Type-C) and powers its cooler from a 12 V DC input.
