Here is a repro of one of my better M83 results from
almost this time last year.
I have a routine now that I use on my better data which involves
a Bspline resize then stack. So I thought I'd try it on some old data.
The sharpening and curves seem to work better on the resampled
data.
This is nice. I do recall your last post on this (hard to tell the difference from memory though). Yes, during registration the image is resampled which loses some detail in the process. By resampling the image up before registration the loss is held to a minimum.
