GSO 10:1 Crayford Focusers
I'm looking at changing the focuser on my 150 Newtonian for a 10:1 Crayford type. Any problems with the GSO ones ? Funds are limited and its within the price range but don't want to end up with something thats not really suitable. The range of adjustment looks shorter on this type of focuser, so would it be advisable to look at getting some extender tubes as well.
Any advice is welcomed.
Bill
