Thanks, Dick, for the reply. Mine was set to 15, but what is crazy, is that the scope was looking at M 1 at the time. It also took a good centering image and it was about 80 degrees elevation. I'll fiddle with it and try again tonight. I've never had a problem like this before. Gremlins. If you think of anything else, please let me know. I will post tonight what happens. Thanks LaVor
