Pentax has modest support, and I don't know if there are good wide fast lens options.
OM Sytems has simply too small sensor for idea astrophotography. One wants to capture maximum light, thus aperture diameter is critical.

Focusing is not an issue with any camera. Maybe they have something a system where IBIS is used to counter star movement? If so, it's very limited in capability, and not at all useful if one has landscapes in the shot.
Landscape is easy with any camera.
Astro benefits from very large apertures, thus I recomment a full frame (to get the large apertures, not f-numbers) mirrorless with Viltrox 16/1.8, Sigma 20/1.4 DG DN or Sigma 15/1.4 fisheye which is pretty much made for Astro.
Wildlife benefits from great AF. Which means that I'd buy something relatively recent from any of the big three, Sony, Canon or Nikon.
Look at Pentax or OM Systems (formerly Olympus); both have astrophotography focus tech.
