I have the same issue with an L-Extreme filter. The problem is the very large halo, which has multiple "rings". I've tried numerous methods, including PixelMath that attempts to separate the halo from the background and then subtract the halo, and/o…
The flats were created a couple of months ago, and I can't remember if they were created with WBPP (version 1 or 2?) or manually via image calibration and image integration processes. At this point I think you've narrowed the possibilities down suff…
Thanks, Adam. AFAIK, using bias for works fine when I do a manual stacking, although I can certainly take some flat darks and see how that goes.
I did click on the flat group, but there was no warning (and diagnostics showed no issue). Also, where i…
I'm also attaching jpegs of the unlinked auto stretched master flat, WBPP processed image, and the manually processed image. There's not only a difference between the processed images, but they also appear to be 180 degrees rotated with respect to e…
Thanks for looking at this. I agree, it's really puzzling that there is a noticeable difference between WBPP and what should be and the identical manual processing steps. I'm sure it's something that I'm doing incorrectly, but I can't figure out wha…
Thanks Adam; I've watched all the Fundamental videos, but must have missed that one. Interestingly, I've been using the same darks and flats for earlier targets, and this is the first time this has happened. This is also the first time I've used WBP…
