Large Sensor Size
The QHY5III485C has 4 times the area of the smaller QHY5III462C and 4 times the number of pixels. In area it is the same size as the popular IMX174 sensor but with back-illumination and higher resolution. The generous field of view provided by this larger sensor makes it ideal for solar and lunar imaging whereas the smaller, faster QHY5III462C with its enhanced IR response is superior for imaging planets like Jupiter, Saturn and Mars.

High QE and sHCG
While the QHY5III485C does not have the extended near IR response of the QHY5III462C, it does have sHGC (Super High Cain Conversion) for exceptionally low (less than 1e-) read noise. For solar and lunar imaging, the NIR response is not required but the ability to take multiple short exposures in H-alpha light is ideal for solar use and making movies of solar prominences, arcs and eruptions.

Combination All Sky Camera

The QHY5III485C standard package includes a 2.5mm
Fisheye lens that converts the planetary camera into
