thanks for your kind comments , i was going to do a 32 image stack but couldn't seem to pull any more data out of the image so i stuck with the single frame

For a 1 min sub, zoomed in, the stars are eggy on the left edge and round in the middle?, polar alignment?.

dont really know , i was aligned as good as i could get but the egg shaped stars on the original uncropped image were all round the exterior so i am assuming it may be an issue with filters or the glass in the refractor , would be interesting to find out what is causing it.
