GSO 0.5x Focal Reducer - 2"
For sale 1 x GSO 0.5x Focal Reducer, 2" barrel. Barely used, screw mountable into the bottom of an eyepiece, or however you want to mount it.....
Once again, purchased, and unused. New Andrews have them for $69, which is probably pretty cheap. Will sell this for $50 with free postage.
Adam.
