StarTools

how did you see the aberrant pixel column?

Zoom into the very left border and scroll down the image. You will see a constant vertical "line". It pays to always closely inspect the borders of your dataset to make sure there are no stacking-related artefacts visible.
For ease, I always crop a good few pixels, even if I can't readily see anything, just to be safe.

you rock, thanks very much for the explanation (and patience with a noob!)

No way this is data from a beginner! It's excellent and deep, with great framing. Some star shape/distortion issues perhaps, but that's really nitpicking. I'm working on something that can help here too. There is lots to like here.

haha thanks for your kind words! But a total beginner. This is my 3rd image ever, and the first from a cooled astro cam. Trying to learn as much as possible, but there's so much to take in.

Looking forward to your upcoming changes. Love this product! It makes the process easier to understand than most.
