I’m going to take a wild guess here, but if you look at your first frame and last frame, does the comet appear to have moved backwards? I’m wondering if the strange plasma you see in the front is just an artifact of the stacked results. Stacking comets can be a bit tricky due to their movement.
That being said, absolutely amazing shot!
I’ve been using the fdroid syncthing-fork version for a long time now and haven’t had any issues at all… Doesn’t mean it’ll last forever but it’s been getting the job done for me even in its current state.
… And can’t remember my original reason to use the fork instead lol
