My GOTOs got worse and worse. I decided to re-polar align last night. I did a rough alignment, punched in Polar align and did best I could. So far so good, GOTOs seemed to be better (not perfect). Then I decided to realign, turned power off, back on and started normal alignment procedure. I chose Two-Star align with Algol as first star. Wheeeeee , the mount went upwards Cassiopea.
I tried a few other stars - all were going WAY off. I checked, tripple checked my time, location, everything looked fine. I wanted to re-polar align, but it required mount to be aligned first somewhat close first. After many attempts, I gave up.
I reset to Factory Settings. Punched in time, location - phewww the scope went roughly towards Algol this time, got in 25mm EP FOV. Alignment procedure went normally from that point. Since I was taking it now very personally and the time was approaching 3AM I decided to do a super fine Polar align.
I was working alignment knobs very very carefully, secured final alignment with a solid twist with Algol (that was my polar align star as well) still in dead center. The pier mount is extremely solid, I tried shaking the whole thing with my weight - alignment star barely shakes in center.
I did another power cycle and realignment. Things looked not bad, but no improvement to where I started. Here is a 60 second unguided frame in the vicinity of Bubble Nebula. This is 1/4 frame crop from image center, through C8 scope with about 0.5 degree field of view.
So the question is - is this expected of the CGEM? Is one minute too long for unguided? Thank you in advance for help.
