The QHY 183C Cooled Color Astronomy Camera utilizes a high-sensitivity 20-megapixel Sony IMX183 CMOS sensor to deliver razor-sharp clarity for serious deep-space imaging. Featuring an impressive 84% peak quantum efficiency and extraordinarily low readout noise, this cooled astronomy camera brings faint nebulae and distant galaxies into brilliant focus with stunning color accuracy.
Advanced Thermoelectric Cooling PerformanceUnmatched Long Exposure Noise Control
Designed for demanding astrophotographers, the QHY 183C Cooled Color Astronomy Camera incorporates two-stage TEC cooling capable of reducing sensor temperatures down to -45°C below ambient. This dramatically minimizes dark current noise during long exposures on warm summer nights. Built-in anti-dew circuitry with a sealed chamber and heated sensor window ensures clear optics under damp conditions. Equipped with a 128MB DDRII image buffer, the QHY 183C prevents dropped frames during high-speed USB 3.0 image transfers, enabling smooth 4K video recording and 19FPS full-resolution capture.
