About the problem of cross-referencing NORAD and international
satellite designations to actual names of satellites: this site

http://hea-www.harvard.edu/QEDT/jcm/space/jsr/jsr.html

has a few files that can help in that regard (one of them
specifically for geosats, some others that are more "general").
One of my longer-range goals is to have Guide use such a list to
take a given TLE file and create a new TLE with names inserted.

Lawrence, about the yellow squares you're seeing: those definitely
sound like nebulae, and Oliver's suggestion sounds right: shutting
off NGC+IC and Messier objects, as well as turning nebulae off, ought
to do the job. Since it doesn't, I have no idea what these objects
are. Therefore:

When you right-click on them, what sort of "short info" do you get?
When you ask for "more info", what do you see? Given that, we ought
to know what these squares are, and should be able to figure out how
to turn them off.
