Thanks for your comments Mike and Trish. What made the difference for me is finding the SubFrameSelector (about 2 weeks ago) Process in Pixinsight, it will graph the FWHM of your stars in each of your Subs which makes it easy to remove outliers Subs where the stars exceed a certain chosen value, as in the above case 2.3". I read in one of Merlin66(Ken) posts, that Melbourne skies have a seeing average around 2 to 2.5" . Having now gone back through some of my past pictures using the SubFrame Selector, I totally agree with him. When I went back and looked at a couple of pictures that have always niggled me because of a slight blur, I found that the stars in the Subs where around 3 to 4". "I have learnt my lesson now" as they say in Engineering, crap in gives crap out.
