Description

I have some strange horizontal banding in my images. It started with the AT115. I'm not sure if it's from the new components or the camera. I guess I'll have to experiment with swapping things in and out of the imaging train until I find it.

Revision B: Reprocessed with new bias and darks. I also added flats and they fixed the banding issue, although they weren't the best flats as the t-shirt had a wrinkle in it. I will fix that after I get more images.
