Description

Man, I continue to struggle with galaxy processing. Just seem to continually run into issues with weird gradients and crazy backgrounds after DBE. I think I might be having issues with calibrating with flats. I'll continue to work on it. I have at least ten times the data for this target than I've included here, but when trying to combine data from different days with different flats, my issues just seem to get compounded.
