Which camera to choose:
Monochrome camera sensors are capable of higher details and sensitivity than color sensors, but
you need additional accessories such as filter wheel and filters. The post-processing is more
complicated too. So color camera is often recommended for 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.
