Hey Guys! 

New here, I am just starting out in Astro, I have a TS optics 6" F4 (154/600), with the TS optics 2" 0.95x Coma max field corrector, shooting with my existing full frame EOS R with M48 RF  T adapter to the coma corrector. 

Is this level vignette considered acceptable/normal for full frame ? Or is there something I change to improve it or is it just a matter of "fix it in post"..

Quick test shot before clouds rolled in, was during alignment of the rig so ignore the trails etc.. 




Thanks!

That's normal, in fact I'd expect it to be even worse on full frame. Take good flats and that will correct for it.
