This sounds like an interesting project. I've been looking for something 
to do with the Meade 4455D telescope I just got. (D=114m F=910, f/8) 
Doing a fixed mount at a know location shouldn't be a problem. I've also 
got an untested Hamamatsu E717-07 photomultiplier tube. Please let me 
know how it goes.
