[APBeta] Star Magnitudes

[Jeff Young]

Tony --

I don't think you're doing anything wrong -- it appears to be broken.  Neither the "Default Limiting Magnitude" setting (which should set the Magnitude Limits sliders), nor the sliders themselves are working for me.

I don't know how long either has been broken -- I use primarily one scope and its magnitude limit is beyond most catalogs, so I'm used to seeing all the stars anyway.
