Subject: ETX-125 AZIMUTH and ALTITUDE REPAIR - broken gear box boss Sent: Saturday, September 20, 2008 23:38:34 From: Roger Gailey (firstname.lastname@example.org) Love your site - it gave me worlds of great input I started to do the fixes you recommend but found I had a problem that did not appear in any other discussions. The screws that hold the brass gear box in place would not tighten. The boss was not just stripped - it was broken and gone ! I wrote up a repair document that is attached with pictures etc. [Microsoft Word doc] I hope this can help someone Next is the project of collimation. I have found a few instructions but what is the best one that talks in super simple basics with many pictures? THANKS Roger GaileyMike here: There are some collimation articles on the Helpful Information: Telescope Tech Tips page. Some have images showing what star tests should look like. None have photos of the ETX disassembled to actually do the collimation; there are just word descriptions of the process.
