Thanks to the prompt response.
I'm trying to remember the settings at this time, anyway I can tell you that I've tried one of everything ...
...auto focus data points: from 5 to 11
...step size: from 4 to 20
...maximum star diameter: from 2 to 15
...crop auto focus frama: from "no" to 50%
...exposure time and ISO: very varied
If I refocus the fire repeatedly the result is always different, the curve is always different.
And then suddenly loses the temperature. (NA in pannel).
What I see during the formation of the curve is that the stars that consider calculating the HFR change, are not the same and so I think that the statistical average does not work well. but these are trivial considerations, I do not know the logic of the program.
What I can say is that if I do not move anything, if I use maximdl and focusmax, I do and refocus the fire ... fast and accurate fire with at most one step difference!
I do not know what to say.
SGPro I really like it very much, it is a simple and powerful solution, if I could solve this problem I would be extremely happy.
