APS-C is a relatively large size among single shot color CCD cameras. The QHY8L is a 6 Megapixel camera with an APS-C size SONY CCD sensor.
SONY's CCD sensors are famous for their low thermal noise. This is reduced even more in the QHY8L by out 2-stage TE cooling and thermal construction design. The QHY8L has the cooling capability of -40C below ambient. This results in the production of very clean images even in exposures of 30 minutes to one hour.
The QHY8L also has very low read noise, typically 6 or 7e-. In a dark site it offers the user a simple and easy way to capture deep sky objects in full color without the need, complexity and cost of RGB filters and filter wheel. The image processing work can likewise be simplified compared to separate processing and combining of LRGB frames.
The QHY8L camera body has a diameter of only 63mm only, making it ideally suited for Hyperstar imaging. It also comes with a cable clip for solid connections. You do not need to worry about contact problems with the USB cable or power cable.
