Description

While minor guiding problems are not affecting nebula structures so much, star clusters are prone to show any guiding mistakes. In the last days I did a bit of progress controlling the Exos-2 with PHD2. At least enough to feel confident enough to show a picture of the famous M13 cluster.

The stars are still not perfectly round, but I am getting much closer. I am not 100% sure what to expect from the entry level Exos-2 mount, but I have big hopes that I will manage to get an average deviation of below 2". The 9 stacked shots I show here were guided with an average deviation of the guide star of around 2.5". For now I am very happy with that!

9 x 180 second frames, slightly cropped.

Best,

Jan
