Simple - the obvious term is astrocamera - as while some even share the same sensors as some cameras, there are numerous differences specific to the Astro application:
- must be operated tethered to a PC to view and control the camera,
- no knobs and duals to twiddle - all controlled remotely from a tethered PC;
- no battery internally, no view finder, no onboard storage, no aperture controls,
- monochromatic (no Bayer filter),
- designed to connect to a telescope, not camera lenses;
- no in-camera controls for focus or aperture, and the big one -
- thermoelectric cooling.
