Can anyone recommend a focus motor?

Mike Greenhill-Hooper All Messages By This Member #696 Hi, I have a 20" f/4 classic Obsession with Starlight Feather Touch focuser (with curved base), built in 2020.? The focuser seems to have quite a low profile.? I was hoping to buy the Rigel Systems nFocus motor as I already have the corresponding nFocus controller that I use with another focus motor / focuser combination.? However, I am worried that the gear wheel on the motor has a diameter that is too great and will not fit on the focuser shaft without touching the base of the focuser. ? Does anyone have a suggestion for a make that will fit and work for my telescope, please?? I am happy to have a hand controller and do not necessarily need to connect to and be controlled by my laptop. ? Cheers, Mike G-H ?

You might get one direct from them or perhaps Woodland Hills or High Point Scientific might have one in stock… Best, Gordon Distressed electrons pushed out by my iPhone toggle quoted message Show quoted text On Mar 12, 2025, at 6:09?AM, Mike Greenhill-Hooper via groups.io <sally.greenhill@...> wrote: ?

I have installed a Primalucelab motorized focuser model Sesto Senso 2 on my UC18 to interface with the feathertouch focuser that Obsession mounted. ? ? I have also mounted their windows PC (Eagle 4S) on the bottom of the telescope so I can remote control the entire telescope from inside my house. ? Richard
