Konus 90mm f/11 refractor - should I buy used?
Posted 26 May 2011 - 09:10 PM
The focuser tube is plastic and seems to be stripped about an inch from being racked all the way in. It is this way reguardless of how loose or tight the retaining screw is. You can push it in while turning the knob and it will continue. The owner knows close to nothing about scopes. He is asking $125 for it. Would it be possible to replace this focuser without a larger expense? What type of offer should I make in light of this defect or should I buy it at all?

I wouldn't mind the scope but I too think it is undermounted but not to a great deal. The focuser WOULD need replacing - not right away necessarily, but in the near future. I will talk to him and let everyone know what's going on. Thanks everyone so far.

Yep,with a warranty. Add a wooden tripod and the setup is useable.
Just saw that Owl Astronomy has a brand new one for 179.95
