Focuser
G’day, I am thinking of getting a new focuser for my Australian geographic 150mm x 750mm Newtonian reflector, the focuser on it is very clunky, so much that the collimator laser moves a good 10mm when going in or out.
Would I be wasting my money modifying such a cheap scope or could it make enough difference for a while until I can afford a new scope?
