The QHY 461M-PH is a high-resolution, back-illuminated monochrome CMOS camera designed for serious astrophotographers and astronomy professionals. Featuring a Sony IMX461 sensor with 102 megapixels and native 16-bit analog-to-digital conversion, it delivers ultra-low readout noise of 1 electron at high gain and exceptional quantum efficiency of up to 90% for maximum sensitivity to dim celestial objects. The compact photographic version offers the same optical performance as larger scientific models with dual-stage thermoelectric cooling, integrated dew prevention, and true RAW image output—making it an ideal medium-format imaging solution for deep-sky surveys and extended exposure work.
