Sorry, can't talk you out of this, Klaus. 
Beyond just star/sky photography it would be great for nightscape photography in general, with or without light painting in combination with great starry skies.
As to lenses, UWA, if you want to keep it "cheap", you could consider one of the Samyang UWA lenses, as a lot of them are great for sky / star photography, with little to no astigmatism, even wide open, beating many of the much more expensive options. There even are AF versions of some of these lenses for EOS.
Of course, they can be used with the Canon adapter on the EOS R as well. And if you'd want, they can be adapted to MFT too, with or without speedbooster .
Persoanlly I am not into sky and star photography, but I do like landscapes a lot, so I went even wider, the Samyang XP Premium 10 F/3.5. This lens is IMO absolutely stellar at F/8, but less so at larger apertures, due to some field curvature and light fall-off in the corners (obviously). However, it is better than the Canon 11-24 F/4L at the UWA side, and comes at less than 1/3 of the price of the latter over here. No AF for this lens, but colour wise they render similarly. It is quite a large lens, however, and F/8 is not really for star scapes, so one of the 14 mm options might be a better choice for you.
Kind regards, Wim
