What is the most suitable equipment for deep space celestial photography?

The most suitable equipment for deep space celestial photography is usually a SLR camera or a mirrorless camera modified by BCF and a CCD or CMOS camera with refrigeration equipment. CCD and CMOS industrial cameras are divided into CCD (Charge Coupled Device) and CMOS (Metal Oxide Semiconductor Device) according to the different image sensing elements. The difference between them is that the imaging technology is different: CCD has only one (or several) output nodes to output data uniformly, and the signal consistency is good, while each pixel in CMOS chip has its own signal amplifier to convert the charge into voltage respectively, and the consistency of the output signal is worse than that of CCD.
