“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
Quote:Because there's no stopper pin to hold the extension in place at the tripod junction, they can loosen in use messing up your alignment. Some folks actually glue'em in place. I just make sure mine is really tight on the Tripod and cross my fingers.Regards,Jim
Quote:Jim don't bother with that measurement, I just talked with Mike at OPT and he put the extension on one the CGEM's they have sitting on the floor. He said it fit like a glove. So I ordered it.Thanks anyway.
