I've had an issue with the SeeStar losing tracking. I do understand that tracking can fail when getting near zenith but that isn't when I'm having the tracking/stacking failure. For instance, while attempting to do a long stacked exposure of NGC 2905 in Leo (the galaxy was approx. 50º alt and 100º az), I was able to get a bit over 30 minutes worth of stack and then the S50 just began to drift causing stacking to fail. I checked and it wasn't anywhere close to zenith, no clouds drifted through, and the telescope had a clear view of the sky. I stopped the exposures, recentered the galaxy, and restarted the exposures. The very first image again showed drift so I recentered and waited a minute to make sure that there wasn't some sort of backlash that needed to be worked out. I then restarted exposure only to see that it jumped quite a bit suddenly in tracking and then drifted a bit again. At this point, I just let it run for 15 minutes or so checking back on it every few minutes and eventually noticed that the drifting I'd seen earlier had stopped. I restarted imaging and it's now been running for nearly 11 minutes w/o an issue. Thoughts on what's happening?
