Looking good Paul. A vast improvement over your first attempt with this data set. More data may assist, but I feel what you've present is in true form. The image doesn't "snap" and has an overall smooth appearance. Perhaps a few subs in the data set not delivering a good FWHM could be removed before the data combine to see if it improves the resolution. Regardless, a solid result indeed. Well done.

EDIT: I'm assuming you know how to check FWHM in CCDStack by registering/aligning the data, then double clicking a non saturated star. This will highlight the FWHM of the same star across the entire stack of subs within the image manager window allowing easy review/removal of bad subs.
