Deep-Sky Imaging ExcellenceHigh Sensitivity Monochrome CMOS Performance
The QHY 183M Cooled Monochrome Astronomy Camera features a high-resolution 20-megapixel back-illuminated Sony IMX183 sensor engineered specifically for serious deep-sky astrophotography. Boasting an impressive 84% quantum efficiency and ultra-low readout noise down to 1e-, this astrophotography camera delivers crisp, detailed images of faint nebulae and distant galaxies. With integrated two-stage TEC cooling that drops temperatures up to -45°C below ambient, the QHY 183M camera ensures ultra-clean exposures even during warm summer observing sessions.
Unmatched Sensitivity and ControlEngineered for Faint Deep Space Targets
Designed for astrophotographers who demand uncompromising performance, the QHY 183M Cooled Monochrome Astronomy Camera combines cutting-edge sensor technology with advanced thermal management. Its 1-inch monochrome sensor packs 5,544x3,694 pixels at 2.4µm size, making it ideal for capturing high-resolution fine details through short-to-medium focal length telescopes. To combat dew and thermal noise, QHY incorporates a sealed chamber with an anti-dew window heater and dual-stage TEC cooling. Furthermore, the onboard 128MB DDRII image buffer eliminates dropped frames during high-speed transfers over USB 3.0, while specialized anti-amp glow circuitry keeps long-exposure astrophotography images clean and free of sensor artifacts.
