I did some research during the day and found I needed to train the telescope motors so the AutoStar knew about the telescope it was connected to. So, I did that. I had hoped to do it during the daylight but did it right before heading outside.
I did the AutoStar alignment and it did seem a little closer but still off. I tried going back to the Great Globular Cluster (M13) using the GOTO and it was nearby but still not centered. So, I was tired from this being the fourth observing night, frustrated with the straight through finderscope and my feet even hurt. So, I decided to call it a night earlier and re-evaluate.
One of my thoughts was maybe the telescope is just old. To be honest, it is over 14 years old and I had never really used it until now. Second, maybe my skies are too light polluted. Third, I didn’t give my eyes a chance to dark adjust. Lastly, maybe I just needed more aperature. I was planning that my next step would be to try some simple astrophotography but that seemed fruitless since I didn’t find any to photograph. Maybe the ETX would be fine for the moon and the planets. Since I figured out how to polar mount, the mounts should auto-track without the AutoStar which was one of the downsides when pointing the telescope out an open window.
I will need to do some thinking.
