Description
QHY174M COLDMOS Camera uses Sony Exmor IMX174 CMOS sensor with 2.35 megapixels on a 1/1.2 inch chip. As a member of the QHYCCD COLDMOS series, QHY174M has the ability to cool 40ºC below ambient, rendering a clean and quiet background for long exposure imaging. The optical window is heated with smart circuitry to prevent condensation from forming during cooling.
QHYCCD Small COLDMOS Series Standard Features
QHYCCD Small COLDMOS camera series consists of cooled cameras using state of the art CMOS sensor of 1 inch or smaller. Equipped with Sony Exmor or ExmorR CMOS sensor and USB3.0 interface, the QHYCCD Small COLDMOS series provides you with an ultra sensitive and high frame rate photography experience. These unique capabilities in compact form factor allow astrophotographers al all levels to enjoy high quality planetary and deep sky imaging.
A built-in 4 pin filter wheel connector allows you to use QHYCCD filter wheela directly without an extra connection needed. A 6 pin guiding port is also provided should you want to use this as an autoguider, particularly for long focal length imaging with an OAG setup.
QHY’s advanced amp-glow suppression technology is implemented in the QHY174 to provide a clean background for long exposure astrophotography, an essential feature for all users planning to do deep sky imaging.
