The QHY5III 290 uses the SONY STARVIS Exmor R back illuminated CMOS sensor. The Starvis sensor is incredibly sensitive, allowing you to see very dim stars in real-time video. The QHY5III 290 can capture magnitude 9 stars when connected with a 50mm f/1.4 C-mount lens. Compared to the IMX236 sensor, it has twice the sensitivity in visible light and three or more times in near infrared wavelengths. 
The QHY5III 290 has ultra-low readout noise as well. The back-illuminated sensor and low readout noise make this camera an ideal video astronomy camera.  The small 2.9um pixel size is also ideal for planetary imaging.
The QHY5III 290 has a "super speed" USB3.0 interface and can deliver 180FPS at full HD output. The camera has a 10/12bit ADC and it outputs either an 8bit image or 12bit image.

Choose from either color or monochrome versions of this camera.
