Full HD Back-illuminated, Ultra-low Read Noise CMOS Camera
STATUS: In stock

The QHY5III290 uses the SONY STARVIS Exmor R back-illuminated CMOS sensor.  Starvis means you can see very dim stars in real time video. The QHY5III290 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 QHY5III290 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 QHY5III290 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.

QHY5III290 is available in both mono (QHY5III290M) and color (QHY5III290C) versions.

“Special Thanks to QHYCCD for their help on technical and software settings. Excellent after sales service of the QHYCCD dealer Cyclops Optics  and very knowledgeable!  The QHY5-III-290M camera is so low noise and more sensitive that I could reduce my capture time. I can finish my session in 15 minutes with superior images vs 45 minutes before! ”     — Chris Go.
