I have written step-by-step instructions on how to attach the EAF to a William Optics Star71, complete with photos. It is possible with the provided hardware (though it can be improved with a quick trip to the hardware store for a longer screw and spacer).

I hope this is helpful to others with this scope and similar ones. I think the instructions should work with any of the WO scopes that have a thermometer in the focuser knob.

That's excellent!

Does not having a focus lock screw after the mod affect performance at all? With my focus lock completely loosened it seems a little sloppy. I usually leave that screw loose enough to adjust focus, but with a bit of resistance.

Thanks!

It doesn't seem to. If it is a problem, you can put the focus lock screw back in its normal place, and buy a 10 or 12 mm long M4 screw to put where I currently have it. The 8 mm long screw included with the EAF is not long enough to reach, though.

Ah, I see. Cool. Thanks for the clarification, and the how-to.
