Thanks Marc Glen and Rick.
The aberration is probably a PI thing from when I did some sharpening. Either the mask I used to protect all stars wasn't quite right or I was too aggressive with the sharpening. I'll go back and have a look. I spent ages processing the wide view image, but not long on the newt image.
I'll have to look into distortion correction. I like the sound of that. I just ordered a new motherboard and CPU - 8 core 8 thread - so hopefully preprocessing with local normalisation etc will now take less than forever and a day with 300-400 subs
Edit. Oops the artefact is in the refractor image. It's still due to the PI sharpening. Same reason.
