Can you get with a friend or two that know how to read schematics?  
Maybe they would be interested in the project too. . .as a way to 
learn some motion control concepts - if they aren't interested in 
astrophotography.

Probably yes, but if you search for surplus electronics catalogs you 
can save $$ too.  Look in the back of hobby/electronics/radio 
magazines for various compaines:  Brigar, C&H Sales, Jameco, Digikey, 
Allparts, etc.
