Hi,
I have some data from when comet C2022 e3 came by, and I’m trying a second attempt at processing since the first was generating severe star trails. I ran thru the tutorial a few weeks back, and it worked great. It was my data; I didn’t realize the 97 images I had covered 3 hours. Anyway, I’m back at it, and this time once I reopen the sequence before any registration, my reference frame is white. This is after I have color-calibrated it. When I set the display mode back to linear, it’s a very light grey. The sliders below the image are set to 0 and 65535. I am using a slightly customized script as I have a master bias, mast flat, and master dark specific to my exposure duration, 60 seconds.
Is anyone else experiencing this issue? I have tried to step through the comet tutorial several times and still have the same result. Below is the script I’m using to generate per-image background extracted files for the comet tutorial. FYI - lights are in their own folder, and the master calibration frames are in the process folder. I can share images once I figure out how.
Any help is greatly appreciated.
