>>4361505Currently having this dialema myself. I also do mild astro but other things like macro and travel pics as well. Think I'm getting an R7 and simply going to buy a second FF body in the future. Technically full frame would be better for your use case but not by a huge enough margin that getting a kneecapped R8 is worth it. I'd go an R6 at minimum if you're going full frame, then keep in mind your full sized RF lenses will be bigger, heavier and more expensive. Technically technically, astro is complicated and bigger nerds could make better recommendations, but bigger sensor is always nice.
R8:

>>4361515I never realised M43 takes such a huge hit even compared to APS-C. I mean, I *knew*, but fark. M43 seems more like a step up from P&S but several steps down from APS-C.
