Product Overview

6.0 Megapixel, 50FPS, High-resolution Back-illuminated CMOS Camera
The QHY5III178 has the highest resolution in the new QHY5III series. This sensor has small 2.4um pixels and a 1/1.8-inch sensor that can be used for high-precison 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 entery level deep sky camera. It is available in both mono and color versions.

For deep sky imaging, the QHY5III178 uses our proprietary anti-amp glow control function that reduces amplifer glow significantly.
The QHY5III178 sensor is Sony's StarVis BSI image sensor. STARVIS is a trademark of Sony Corporation. 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.
