Cosmic Snake – Mandel Wilson 9 Nebula with IC4635

This was taken from the Kagga Kamma Remote Observatory in April and May over 25 sessions in 22 hours with LRGB filters. It's not really called the Cosmic Snake but I'm calling it that.

You can see the full res version of this on Astrobin: https://app.astrobin.com/?i=qbbxwm

And this was stacked and mosaiced automatically using my new Siril script: https://youtu.be/meX8yNV1rYc

As you can see, there were some very heavy light leaks. Did my best to work around them and took me a while to get something I'm happy with. The jagged mosaic panels were also a mistake on my part, I forgot to reset the angles when creating the mosaic sequence in NINA but I think it looks kinda cool, it kinda goes with the body of the snake. We're reimaging this with another rig now with no light leaks. The Esprti's light leaks were also fixed but we were only testing that rig so I won't have access to it for too long and didn't want to start any long term projects there. I think that rig will be ready for rental soon!
