Special clearance price HK$1,190 (50% off)
QHY5-III-290 is currently the best performing planetary camera. It uses Sony STARVIS Exmor R backside illuminated IMX290 CMOS sensor. The Starvis meets the criteria of revealing very dim stars at real-time video rate. QHY5-III-290 can capture magnitude 9 stars when connected with a 50mm f/1.4 C-mount lens. To compare with the IMX236 sensor, it has twice the sensitivity in visible light and three times more in near infrared wavelength.
QHY5-III-290 has ultra-low readout noise. The backside illuminated sensor and low readout noise make this camera an ideal planetary camera. The 2.9um small pixel size is ideal for planetary imagers to achieve high resolution sampling.
The USB3.0 super speed interface and fast readout circuit design allows 135 FPS at full HD output. The camera has 10/12bit ADC and it outputs the 8 bit or 12 bit image respectively.
