Absolutely stunning work! You really picked up 
lots of faint background galaxies. The RG200 really
seems to do well with the blue objects.
 
I have a Tech Pan image of 7331 and Stephan's Quintet
taken with my 10" f/6 Newtonian. This image doesn't
do nearly as well with the fainter background galaxies
even though my exposure times totalled out at 320
minutes.<g> Of course, the smaller aperture and murky
skies didn't help either.

I was wondering if your 14" Cass. provided enough
field to squeeze the Quintet in with 7331?

Thanks,

Scott
