QHYCCD QHY5-III-290M Monochrome CMOS Telescope Astrophotography Camera
This is a full HD back-illuminated, ultra-low read noise CMOS astrophotography camera. The QHY5III290M uses the SONY STARVIS Exmor R back-illuminated CMOS sensor. Using a STARVIS means you can see very dim stars in real time video. The QHY5III290M can capture magnitude 9 stars with a 50mm F/1.4 C-mount lens.
Compared to the IMX236 sensor, for example, the IMX290 has twice sensitivity for visible light and three or more times the sensitivity in near infrared.
The QHY5III290M also has ultra low read noise. The back-illumination and low read noise make this camera an ideal video astronomy camera.
The small 2.9um pixel size is also ideal for planetary imaging.
The QHY5III290M has a fast USB 3.0 interface and produces 135FPS at full HD output . The camera has 10/12-bit ADC and it outputs an 8-bit or 12-bit image.
Available in both mono (QHY5III290M) and color (QHY5III290C) versions
