Thanks Mighty-Oz, Fred, Frank, Rob, Paul, Andrew and Allan!
I love that little grouping of stars to the right so thought I would make it a part of the composition. I think it works pretty good for M104..
Still a lot to learn in Imagesplus, so hopefully things shall only get better!
Mighty-Oz, With the 40D you can set the iso to 1/3 stop or 1/2 stop via the menu.
Thanks again for the positive comments..
