About an hour of 60s subs, Nikon D7100, Nikkor 18-300 @200mm.
Lots of LP so had great difficulty pulling the comet out of the image.
Tried DSS to stack it first and ended up with a mess :(
PixInsight produced far better results.

Started by masking out all the bright stars in the star-aligned subs before comet stacking. This greatly reduced the smudges left by the stars. (Tried the min/max method of integration to remove the stars but because subs were wide field and close together it didn't work too well)
Once I'd managed to pull out the comet i then merged the stacked stars back over it.
