I am having problems with the Celestron Starsense alignment device and my mount, a Celestron Advanced GT which I got used a few months ago. I added a two screw saddle to improve the security for the scope, but do not think that should have changed the alignment process. My scope is a Nexstar 8SE.
I polar align the mount using the polar finderscope, bring the mount to the home position, and do the Starsense autoalignment, which seems to work. I then attempt to calibrate the center using Polaris. Is out of the field by a few degrees. I go through the calibration, and then realign the mount, as instructed. When I again do goto to Polaris, it still is off by about the same amount as before the calibration. I tried this several times with the same result each time. I now am wondering if there is problem with the mount?
