Description

Because I planned to go for a rather faint structure in the Draco region as my first LBN-target and due to the small aperture of my optics, this undertaking would become my first attempt to image a target over multiple nights.
Since my rig is not permanent and has to be installed and set up for each session I wasn't really sure if my plan would be achievable and I was further uncertain of the procedures that will be required to get the same framing each night as well as how to stack the data from multiple nights. I invested a total of seven nights where I encountered various challenges and issues, so due to troubleshooting and failed attempts it resulted in two nights with no data collected - in the end I managed to image on five different nights. For preprocessing I went with WBPP for the first time instead of DSS.

In hindsight I'm glad that I had stick to my plan and hadn't aborted it, because I was able to gain routine and learned valuable lessons that I wouldn't have otherwise.
