I'm building an "annex" to my ROR that will be used for remote operation for DSO imaging. This will include my AP 130mm GTX on a Mach2 mount. I'd like to add a small refractor for very wide-field DSO imaging. In the past my Vixen ED81S served this role quite well.
Here is the problem. If I am imaging remotely I won't be able to adjust focus. The AP 130mm GTX is setup with a Feather Touch Microfocuser that I can control with SGP. However, I don't have that ability with the Vixen ED81S with its stock dual-speed manual focuser.
Is there a way to add an motorized focuser for the ED81S that I can control through the SGP autofocus routine? I've looked around and haven't found one yet.
