Thanks for picking this up, it slipped past me. Looks like a combination of a few factors; that being subtle guiding error on a couple of nights in the luminance data, coupled with slight focus error which provides some elongation in star shapes. There was also a slight issue with balance, which might have been present when I took this part of the data as it is not present in the data taken since this adjustment. The scope is a bit of a pig to balance with the filter wheel slight offset. I have made corrections to the star shapes now.
