You have captured a great image with your ETX70. What camera did you use and what mount did you use?

:oops: I wouldnt even dare try it with my equipment, the img is copy paste but made it as dark as i see it. To show you how i perceive it.

Aye true, all depends on F. It will change if you make a scope depending on what you want it for say comet hunting or planet viewing. Though generally the bigger the scope the bigger the FOV

Of course then you have the likes of Mr. Pete Lawrence taking a few shots of andromeda with his 80mm refractor

Granted, its a good 80mm refractor, but an affordable one. And by a few shots I mean 55 of at least 60 seconds each with a canon 20Da.

I think what we are trying to say here is

The bigger the scope for a given F ratio the smaller the field of view.

I feel better already!
