QHY165C
16 Megapixel APS-C Format Cooled CMOS Camera

The QHY165C is a lower cost version of QHY168C.  It uses the same APS-C format 16 Megapixel CMOS sensor with 4.8um pixels.  The only difference is that the QHY165C has a 12-bit ADC whereas the QHY168C is 14-bit.

Here is a thing you need notice,because of some reasons,this software for Mac version didn't attach a necessary library,you need add it by yourself.You can click here to download that library,and unzip it to /usr/local/lib,and if you have installed libusb library in /usr/local/lib,you don't need do this.

QHY165C Performance Charts
It is very important to understand the "unity gain" concept for CMOS camera, and how to select a suitable gain for capturing images.  Gain is usually expressed in terms of the number of electrons per ADU (Analog to Digital Unit).  Unity gain is the level of gain which corresponds to 1e-/ADU for a particular system.  Lower than unity gain setting will cause some sampling noise. The QHY165C unity gain setting is 3750.

For deep space imaging, there are two methods that can be used.  One is the traditional, long exposure, DSO capture method.  Another is the so-called "lucky imaging" method using short exposures to avoid periods of bad seeing, and high quantity stacking.  For long exposure, you can use the lower gain to take advantage of the higher full well capacity and avoid saturation of bright areas and stars.  For lucky imaging you need to use high gain to reduce the readout noise and avoid the sample noise.
