I'd like some advice about a good electronic focuser.

I am wanting to fit it on an AP130GT which has a 3.5 inch focuser and feathertouch fine focuser.

I have read there is an Optec unit that is good similar to (or the same as) the Feathertouch HSM unit. I have one of those on another smaller scope and it seems fine.

Suggestions?

Greg.
