Well this has been quite a journey to get to this image. For a while now I have been in talks with an observatory in/close to my home town. Both my parents were involved with the astronomy club there in their youth. So I asked them if I could use their telescopes to capture images.

Honestly I did not expect them to reply positively to it. Apparently though they were amazed by my captures posted here on astrobin. So I feel really lucky. I try to share as much of my knowledge that I can with them, especially on automation, something they do not have a lot of experience with.

This the first image I took (with help) with a very good high resolution setup there. One of the members of the local astronomy club Martin Fiedler even helped me with capturing subs when I could not make it to the observatory. So thank you!
