Hi Larry!
Thank you for the very interesting project. I tried to use your program and I have several questions...
1. Can Unimap read some parameters directly from FITS header? For example OBJCTRA, OBJCTDEC (or CRVAL) and information about image scale?
2. What do you think about add UCAC3 support?
3. I tried to load asteroids in the field, after very long process (fetching ASTORB data from Vizier, translate it to local format and sorting) Unimap stop respond...
4. Can I manually measure astrometric position of object on the image?
