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.
G'day Andrew,
I already have quite a collection of databases including TCHO2 and others, but I'm having trouble figuring out how to get UniMap to access local copies of those catalogs - the TCHO files are DAT files whereas the UniMap data files seem to be in another format with an ADM suffix.
I had hoped to be able to make the system free-standing so I can use it in the field without an internet connection and accessing SINBAD and so forth remotely.

Peter
