Anyone used Full Frame on Orion 8" F3.9

Hi

I use a 550d (APSC) on an Orion 8" F3.9 which works well.

Ive got the opportunity to get a full frame DSLR for Landscape etc and wondered if it would work well on my scope

Has anyone used a full frame DSLR on this scope.
Vignetting?  More coma in corners?

Thanks

I haven't tried it but would be amazed if you got a distortion-free field on full frame with this scope. I'd put it down as extremely unlikely. However, you can always crop if your main purpose for buying the camera is to use in for landscapes. I've been using full frame chips in astronomy for some time now and relatively few scopes can cover them. This includes a few which say they can but can't!

OK thanks  for that. I had suspected something like that. Its a big ask I guess for a scope or lens to cover that big a sensor with min distortion and vignetting.

I decided to stick with my crop sensor, driven mainly by my lack of good lenses to use with it.
