The object in question is the Bubble Nebula, NGC 7635.
I actually posted scans of the 2 prints in question a
couple of weeks ago. Those should be in last months
archives, if they're available yet. I can't give you
the URL because I just deleted it from the folder I
had it in. However the link is still active. The
Bubble is in a good location and long exposures are
possible.

There was a thread on MAPUG awhile back and it was
explained that even with all the stuff we add to the
scope's business end, it does not increase the f/l
much at all. I'm using a 12" LX200 with a Taurus T
III.

It is a truly impressive film in that regard.
