Mike,
This is a very useful freeby program - Aladin - I use it often:
http://aladin.u-strasbg.fr/java/nph-...me=downloading
Download the file, run it and type NGC7590 in the "command" window. This will centre the screen on NGC7590, from the "File" menu you can load as many catalogs and survey image overlays as you want (there are 100's available). For stars I would choose the USNO B1.0 catalog as it goes all the way down to mag 21.
