Newtonian focuser upgrade recommendations?
Looking to upgrade the focuser on my Skywatcher Black Diamond 200mm f/5 scope. The current focuser is single speed so it's a bit frustrating to find best focus at high powers when observing the planets.
The obvious upgrade is a dual-speed model but I'm wondering about some kind of focus motor, either built in or later add-on.
Any reasonably priced suggestions? Budget is maybe $200.
Cheers.
