Cheers Colin. Just seems unusual to me that in the magnitude is inconsistent, and the bloat seems to be mostly in the direction of RA, where I've been having tracking/guiding issues. Maybe Ray's onto something though in terms of the focus being a bit off on the worst one, worsening the effect. I'll try rotating the camera and see if it still appears in RA or if it moves.

Cheers Rex, good thinking. Unfortunately I wasn't dithering during these captures.
