Does anyone know what might be causing this green banding? I’ve never encountered this issue before, and it disappears when I exclude flats from WBPP. I have inspected my flats, and they seem normal. I’ve yet to try retaking the flats or do more testing. Just hoping someone has seen this before and knows. This is the stacked image from WBPP, including biases, darks, and flats.

No clues, but channelling Andrea - I would try to do the stack by hand, outside of WBPP, to see where things are going wrong…
This looks like registration doing it’s thing. Blink your images, I think your framing is jumping around. The green areas are just a lack of signal.
Just a guess. If not then I’d lean towards a USB issue. This is not a flat or bias issue.
How do the masters dark and flat look like?
I think it may have been a USB issue that affected the flats. I noticed that one of the flats was actually an empty file, so something must have happened while writing to USB (ASIAIR saving to USB). Nonetheless, if I have a look at the master flat from this data, we see the exact pattern present in the master light. If I exclude flats or use flats from a different night, no issues.

Blinking the flats doesn’t reveal anything, at least not easily noticeable. Must have been the subtlest of errors in the files that, when stacked, give me this.
Thanks all
