Which camera to choose:
Monochrome camera sensors are capable of higher detail and sensitivity than is possible with
color sensors, but you need additional accessories such as filter wheel and filters. The
post-processing is more complicated too, so a color camera is often recommended for the beginner
of astrophotographer.
TEC cooling will help to reduce dark current noise for long exposures. For short exposures,
such as under one second, the dark current noise is very low, however cooling is recommended for
DSO imaging when long exposures are required.
