I interfaced to a substantial database which was essentially a catalog of stars and interesting objects (Messier objects, etc.) associated with their right ascension and declination positions on the celestial sphere. But at that time I was not using object positions to orient the scope; it's equatorial mount was nominally aligned to a polar axis, and I was using shaft encoders, step counts, and a time reference to drive the scope to find those objects.

This was quite a few years back (mid to late 1980s?), Stan, so I am a little "fuzzy" when it comes to remembering all the details.

I was using a monochrome CRT IBM PC running at that time on what was probably an 80186 processor. When I got involved, the institute had unfortunately already contracted for some custom stepper motor driver hardware that was kinda quirky. The firmware was closed source, and I had to disassemble it in order to fix some severe bugs that popped up. :O

The institute eventually replaced my original software with some more visually oriented star-map type stuff. Nevertheless, that project was some of the most fun I've had during my long and very sketchy career. :D

Summarizing, I would absolutely love to help you with pointing control for orienting missionspace.one telescopes...
