Konus Focuser.

Wanted to get these pictures published for linking purposes.  but since I’m posting, I’d better tell the story…

I purchased a laser collimator, and tried it out on the Konus scope only to find that by working the focuser the dot on the primary mirror was moving like 2-3″ each direction.   No wonder I was having issues with this scope.   I ended up getting it all tightened back up and working within a decent tolerance window, but alas the scope still has the focus / halo effect so the mirror is indeed spherical.  I have nothing else to try now.

Anyway here are the pictures… – Tobin
