With 44 megapixels and 4.4 μm pixels, it delivers incredible resolution and light sensitivity in every shot. The full-frame format lets you capture the entire field your optics can deliver - no cropping, no lost edges - perfect for wide-field targets and large deep-sky objects. Each pixel supports a full-well capacity of 74,600 electrons, providing exceptional dynamic range. Bright stars retain their natural color and detail, while faint nebula structures and galaxy arms remain beautifully visible.

This protective filter blocks unwanted ultraviolet and infrared light that can cause star bloat and color distortion, allowing only visible wavelengths to reach the sensor. By filtering out these non-visible wavelengths, the camera produces sharper stars, more accurate colors, and overall improved image quality in astrophotography.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eProduct Details\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull-frame back-illuminated CMOS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensor Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e36 × 24 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDiagonal\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e43.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e44 MP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePixel Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.4 μm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFull-Well Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e74,600 e⁻\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantum Efficiency (QE Peak)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e80%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eADC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e14-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDynamic Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;13 stops\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHCG Mode\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eActivates at gain 136;
