I wondered - since I had about 75 luminance subs of NGC253 if I could possibly extract more detail from them by performing a drizzle integration (x2) using PixInsight. So following the procedure on the PI forum by Juan Conejero I aligned, drizzled and then stacked them quickly.
The result is a severe crop of the resulting image, but I think you can see that the dust streams and finer detail is much improved in this final image. I have included the original colour version for comparison.
