When you shot those images did you use a field flattener?

For a grab and go I use the ioptron skyguider pro. The internal battery lasts about 20 hours so I so I can do multiple sessions before having to recharge it. I use it with a couple of nikons and some prime lenses that I have. You can check the classifieds here and and the other site and normally find them under $400 is dollars used. The hardest part it's actually locating target With longer focal lengths. This was about an hour worth of data with a mediocre polar alignment at best best 32nd shots in shots F 2.8 And on top of that I don't have the best processing skills I'm still learning.

Are you using windows 10? I recently pulled mine out after 10 years and it does not like windows 10. Works fine on windows 7 though.
