6.0 Megapixel, 50FPS, High-resolution Back-illuminated CMOS Camera
STATUS: In stock

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.

The unique QHYCCD design retains the 1.25-inch eyepiece design of the QHY5-II but adds features for improved thermal efficiency. The advantage of this design is better transfer of heat to the outer case enabling lower noise especially in high ambient temperatures.  The 1.25-inch design also offers the shortest possible backfocus, making the camera ideal for off-axis guiding.  In addition, the QHY5III178 uses the more robust LEMO style connector for the guide port.  These connectors are known for being both rugged and reliable connectors.
