- 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.
Indeed these reasons in bold are why I don't want an astro camera.
I don't know why it is in 2018 not possible that these cameras can not work with builtin SD card, battery, basic controls and even no smartphone app. A small device like a smartphone or tablet is much easier to use in the field.

A modern SLR is much more versatile for astrophotography, modern sensors (particularly the Sony A7 series) are very sensitive and no cable jungles.
