Focuser upgrade for Starhopper dob
Well, it's been too long but I got the scope out last night and had a great two hours. Saturn was wonderful - although the ring plane has closed up a lot since I last viewed it. Six stars popped up in the Trapezium, and I fancy I even glimpsed the G star once. A pleasant hour with O'Meara's book on the Caldwall objects around rising Crux.
Anyways, the clunky old focuser on the clunky old Starhopper (the old cardboard tube model) is annoying me. Compared to the Crayford on my refractor, it's stiff and sticky.
What are some focuser upgrade options for this Dob? Suppliers? Easy to do yourself?
Cheers
Doug
