Could you make a bracket and fit an EAF to the original Meade focuser shaft? I have the Celestron focus motor on my SCT and while it does OK, if I was to go again I would make a bracket and figure out a way to mount an EAF on it as it is more consistent than the Celestron motor and includes a temperature sensor which the Celestron motor does not. That is a big omission IMO given how sensitive an SCT is to temperature changes inducing focus drift. When I use the SCT and expect substantial temperatur changes over the night I have it doing a focus run about every 20 minutes due to not having the temperature sensor to trigger it and even then you can get some out of focus subs early in the night.
