Gemini Automatic Astro Focuser Pro EAF - Unboxing, Install & Software

[@MatthewHolevinski]

I've had one of those for a couple months but haven't even fiddled with it yet, I'd like to figure out how to get it on a big guide scope like that svbony 106 with the helical focuser.

I'm not really sure if putting on a guide scope with a helical focuser is worth the effort, but it could be done. You would need set it up like people do for camera lenses - making a mounting bracket of some type for the focus motor, install a gear of the appropriate size on the motor & run a drive belt around the helical focuser. A lot of work for the small movements that would be required. And generally you won't need to change focus on a guide scope very often at all once setup. Cheers
