I think the fundamental issue with my data is:
– subs too short, I will try 60 second subs, but not guiding so will have to get the PoleMaster out
– I stupidly shot in JPEG and need ot shoot in RAW
– I think the comet will be better when higher in the sky.
Here is one of my many stacks, where I forgot to identify the comet as a comet and it’s just stacked on the stars!
