Just curious if you've experienced something like this while using WBPP.
On two consecutive nights, I photographed M42. The only difference in equipment between the two nights was the filter used. (Same camera, target, framing, binning, exposure and number of images).
During WBPP, a couple processes took very different amounts of time to complete between the two sets of data. I've posted a screenshot of the WBPP results.
As you can see, the "Debayer" step for the first night took just under 15 minutes, but for the second night it took over an hour.
At the "Integration" step, the first night took over 12 hours while the second night took less than 3 hours.
Is this my computer? or something about the data?
Anyway - as I say - I was just curious about it as there is no real problem. Everything was successful and the results were good.
