Thanks Aaron,
That picture does help. I have to say I am very nervous about ordering a motor. I'm worried it's going to be the wrong speed, or that I have trouble attaching it because it is the wrong shape. It's not much though, so I may order one today that I can run on a 6v. AC worries me (electrocution), so it definitely needs to be DC.
Also, I need to get some gears, the middle part of the gear, how do I know if it will fit into the motor?
Can anyone recommend/link a motor (DC) and the gears that should be workable?
Thinking this one? :

I don't think I want any electronics/programming on it.
I have found a supplier of gears, just not sure what to match up. (

I took out the camera for a test run last night at 135mm with a Minolta 28-135, which is truly an exceptional terrestrial lens - but it's a disaster for Astro.
This has really made me appreciate the 100mmm f/2.8 prime I am using, which flattens so well and is free of chromatic aberrations..
First shot is with a UV filter on the front (forgot to remove it)
Then, without (not that it really helps given that lens).
