subtle jolt Why’d you clip the background?

I did background subtraction on each of the images because I'm doing difference image photometry (I took this data for science, am an astro PhD student). There is some circular banding around the cluster that's visible after a lot of stretching. The only way to get rid of it was to clip. I could redo this with the pre-subtracted images and that would probably look better

Tried running NoiseXterminator on it

#

yh, I went back to the raw, unmolested data and tried again. Looks pretty good I think
