Celestron 8x50 finder problemPosted By Don Wyman |
I have several of those type finders. If it has .96" eyepieces then it is original and not converted. Yes my friends, they used to actually put real focusers on finders. This finder should have come with a .96" reticle eyepiece. Not sure if 20mm is the right size. How close are the objects you are trying to focus? Have you tried it on stars? I've attached an image of a similar Meade 8X50 with helical focuser.
