User Manual of 32bit Image Data(for QHY600,QHY268,QHY411, QHY461)

SDK version 2021.7.6 later supports the 32bit image data accquirement function. This function is useful for the 16bit cmos like QHY600,QHY268,QHY411, QHY461. When 2*2,3*3,4*4 binning the data range will become 18bit, 19bit and 20bit. Since it exceed the 16bit range, we add the 32bit data transfer function for these cameras. How to get to know the camera support 32bit image? The IsQHYCCDControlAvailable(qhyccd_handle *handle, CONTROL_ID controlId)
