The JMI microfocusers are the ones that have been the defacto stand-alone electronic focuser that fit over the existing focus knob. Check around with a few vendors and, CN classifieds, and Ebay... the scarcity is due to the **** trade war in my opinion because these shouldn't be hard to get. JMI sadly sold out last year and they really were THE guys to go to for this kind of thing. Since you have a 6" the only other option would be to go for an external focuser and get a motor drive for it.

Pegasus Astro makes a couple.
I have the separate focus controller and focus motor, but there is also a combined 'FocusCube.'
My only dislike with the system is that there is no quick release to allow gross focus change.
