Re: (IAAC) limiting magnitude



Jeff, et al;
The latest version of the Saguaro Astronomy Club database does
have calculated values of surface brightness included.  I have
not taken the time to use them alot, but the few times I have
paid attention, this data seems to provide a pretty good
representation of how easy or hard it will be to see that
object.  They were calculated by Dr. Harold Corwin, we are
working with him on the NGC project.
The data is on the SAC archive:

Hope that helps;
Steve
