I fully understand, and appreciate the feedback. I'm going to think about this a bit, but you are correct; the noise just doesn't look right. I'm going to go with the fact that the transparency that night was just poor. Given that, I will assume tha…

Problem resolved. I got WBPP to run the full stack, including LN, with no issues. Unfortunately, it's the same rainbow gradient. I'm uploading both a screenshot of the integration and the log. Any thoughts would be appreciated. Additionally, here is…

Hi Adam. Thanks for the reply. You know, I've probably gone thru this stack 10 times since I posted that first XISF and, frankly, I was tweaking a lot without being very consistent. Let's re-baseline. WBPP kept crashing with memory errors upon integ…

Hi Adam; I know you have little interest in this thread, but I have hit a wall. I've have been doing this 3 tears and have never come up against this "rainbow gradient". I have also always trusted PI and never really was much interested in the math.…

I'm closing this topic with information in the event others search for this type of problem but cannot find help. The flats were always calibrated. My concern was whether I was calibrating them properly for blue-sky dawn flats. In the end, there rea…

I calibrated the flats using a master bias and a master dark (optimized/calibrated). I also attempted putting all the raw frames (lights, flats, darks, and bias) into WBPP and got the same output.

Sounds like a plan and I do appreciate you helping me figure this one out. Full disclosure; I previously only shot flats and flat darks, no bias. So this is the first time I've ever tried to integrate using bias (subtracted from the flats). I will s…

Yeah, I've looked at it several times, but I'll give it another go. It is the first time I've used true sky flats so that might be factor. I wonder if using a pedestal during calibration of the flats makes sense? And please tell me what you are se…
