Ask a Question About This Product

The QHY5III178's sensor is Sony's STARVIS BSI image sensor. BSI means the sensor is Back Side Illuminated, which dramatically increases the sensor's sensitivity and produces high picture quality in the visible-light and near infrared light regions. 

This sensor has small 2.4um pixels and a 1/1.8-inch sensor that can be used for high-precision guiding data with a good FOV for easily finding guide stars.

The camera is designed to be a wide FOV autoguider, high-resolution planetary camera, and entry level deep sky camera. 

For deep sky imaging, the QHY5III178s use QHY's proprietary anti-amp glow control function that reduces amplifier glow significantly. 

The QHY5III178s have the highest resolution in the new QHY5III series.  

Available in both color and monochrome.
