I took about 180 1-minute images of the Cat's Eye nebula with my Canon T3 and have a linear artifact in my green and red pixels. I tried linear defect detection and subtraction, but it had no effect.
The crosshatch in the background is from my attempts of removing horizontal and vertical defects. Any suggestions?

Charlie
