Hello to all
In order to better characterize a 1.3m diameter telescope (focal=9398mm), we would like to use the WavefrontEstimator from Pixinsight. For this, we followed the recommendations by defocusing (intra and extra focale) and produced nice donuts (the test camera is a SBIG ST8300 with a pixel of 5.4 um). Despite our best efforts, we are unable to process the images and have the following error every time: "the defocused image diameter is too large.".
If we make a weaker defocus, it works very well, which makes us think that there is a parameter badly adapted to our telescope. Does anyone have an idea of the problem?
Thank you very much for your help.
Best regards
