Anyone else having a fling with this program?

Peter, if you open the "Options->Catalogs" menu you can add other catalogs for stars, DSOs and all sorts of other objects. You then choose one of the others as the current catalog.
Tycho2 is usually enough and you can download the whole catalog. The bigger star catalogs ones below that in the list are probably better to just download the bits required as required. You do need to have a reasonable guess at the field centre and FOV or you'll have to download a bigger area and that can take ages. It does cache the bits it has downloaded.
Be warned, with a large FOV even Tycho2 can crash it by running out of memory. We had that discussion a couple of week back with Marc's mosaic. I had to reduce the max magnitude to about 8 before it stopped crashing.
