NGC253 more data and reprocessed

I now have more data on the Sculptor galaxy and think this version is a better process. Less over sharpened in my opinion with more fine detail showing. Some elongated stars but this is due to flexure.

I used the Spiegel teams version of this galaxy as a guide. It is probably the best amateur image of NGS253 I have seen and my imaging has a long way to go before I can possibly match these guys.

As of note I am really impressed with the STL11 which requires little subs to produce good results. Although I am having some trouble with removing the column defects. I redid my darks and this helped but do I need to redo my bias frames too?

Anyway to the image.
