I'm looking for a focuser motor to put on my William Optics Megrez 80 (SD, the original version). I'm just after something very simple and low-tech. I have RoboFocus on my LX200 but it's too expensive and more than I need for the Megrez (portable setup). The focus knob of the megrez can be taken off to just leave a shaft able to be connected to.

I'm really just after a motor with fixed or variable speed that can somehow turn the focuser knob, and be controlled by 2 buttons (in and out), or through a computer.

One option I have found is the Orion Acufocus. This looks ideal except I am unsure if I can somehow mount it on my Megrez.

Another option I considered is putting something like a meade micro focuser between camera and 2" draw tube. This is not preferred because it takes up extra back focus and is more expensive, assuming I can mount it on a 2" draw tube.

I have even considered buying a stepper motor kit from Jaycar for $49 which plugs into the computer's LPT port, disadvantage here is it isn't made to fit the scope focuser and would need some sort of gear (minimum $90 from Farnell, if it fits the motor).

So, could anyone offer help:

1) anyone have one of the Orion Acufocusers to take a close up photo and measurements of it's connector?

2) anyone have other suggestions?

Thanks,
Roger.
