Re: Is there some website that will allow me to plot star maps with labelled magnitudes?

I am interested in observing some of the many Hamburg

where I can create such charts? I would need a
limiting magnitude down to about 15.0 or so.

No such software is possible. The deepest catalog with genuinely
reliable magnitudes is Tycho-2, which is more or less complete only
down to about mag 11.5.

The best catalog currently available is USNO-B1, which goes plenty
deep, but only promises photometry accurate to +-0.3 mag -- not very
impressive.

There are several software packages that can import the USNO catalogs
and print maps from them.
