The native resolution of your image looks good.
None of that "over processed look" which tends to make the
highly-foreshortened spiral arms of this galaxy seem much thicker than they are.
Good images like yours seem to show that the two principal spiral arms are in reality rather thin, though there is a lot of confusion from a heavy dust screen within this galaxy that builds up due to its unfavourable orientation.
Also, the dust streamers rising up at right angles to the principal plane of this galaxy are well seen in your image: what Malin called a "boiling, steaming interstellar medium" in his picture processing paper about the dust distribution within NGC 253.
Would you say that the HII regions in this galaxy are small?
(It is known that much of the Massive Star formation in N253 is concentrated in the central region, highly obscured by dust)

Hello Robert,
I suppose the HII regions are small compared to the size of the galaxy. M31 springs to mind as well. At the other end of the scale is NGC604 in M33.
Unfortunately the ST-10XME is a tight squeeze for NGC253. I might consider a two panel mosaic in the future.
Clear skies

Indeed - just a little more space around it, and voila! A gorgeous image as-is, just tends to distract the eye a little in terms of the crop - maybe that's just me
I guess in about 65 years I may be able to image like that... but by then I'd likely be floating thorough NGC 253 as an aethereal soul instead of looking through a 'scope
