Here is my 2014 version of NGC 253.
There is plenty more data here than last year's effort. That said, I'm struggling still with PI to get a crisp result. ATW seems to make sharp stars with feathery halos and I'm not sure how to wind back the sharpness while keeping a crisper edge.
Comments are most welcome.
A high res version is here:
