We all have some expectations when making the decision to purchase a new gadget that is talked up by a vendor or by another amateur who may possess completely different equipment, skills, and experience. There is nothing worse than realizing later that what you bought did not meet those expectations. So, in this chapter, we will look at cameras capable of producing deep-sky images and the various essential functions and features that are important to ensuring they are up to this task.

2.1 Image Accumulation Cameras

The great innovation in video cameras for use in deep-sky astronomy has been the development of short-exposure image accumulation technology. This internal exposure co-adding technique makes it possible to observe faint detail otherwise nearly impossible to see at the eyepiece and to make a deep-sky portrait from light-polluted urban areas. Moreover, the short exposures mean less stringent need for perfectly polar-aligned mounts or correcting periodic tracking errors....
