How to analyze and fix ISSUES from a FAILED astrophoto session!

I had some issues with my previous astro-imaging session, when I was photographing the Butterfly Nebula. Time to look back, check what happens, and find things to fix so that it will go more smoothly next time!

Looking back at previous sessions is extremely important in astrophotography! So this needs to be done almost every time!

PHD2 Log Viewer is available here: openphdguiding.org/phd2-log-viewer/

Further stuff found after shooting this video:
- wrong foldernames in NINA that needed to be fixed
- connect second instance of NINA to telescope, so the coordinates are saved in the light frame headers
- set Warm on sequence end for the secondary imaging train
- 50mm lens is too widefield so that dithering didn't actually affect it!
