The problem with the data upload limit for attachments has been fixed. I have restored it to 30MegaBytes. A recent forum software upgrade was responsible for the changed limit. Please accept my apologies for missing this when upgrading the forum sofware, Mabula.
Is something changed in the light pollution removal with version 1.074.1 ?
I am asking this because I was trying to do this with a vignetted image of a Canon 6D Mark II, and it gives unusable results. Am I doing something wrong ? I have left flexibility at 01, but this was sufficient in previous versions. On the right you can see the select boxes, on the left the result after caclulation. The vignetting pattern looks very symmetric to me, why do I get this result ?
Thanks for any tips,
