Hallo Nicolàs,
Het principe is gelijk aan een autofocus routine in programmas. Wat ik ook moet vermelden is dat de stap grootte constant moet zijn. Hier in het Engels een korte toelichting:

For the images to analyse in the “inspector tab”, please use a fixed focuser step since for all curve offsets the same weight factor is used in curve fitting routine. It is possible to make more then one exposure per focuser position but do the same for all focuser positions.
For example if your focuser is focused around position 1007 and the range to reach hfd=12 on both sides is 900-1100 do the following:
move to 800 {to remove backlash}
move to 900 and make image of 5 or 10 seconds exposure
move to 910 and make image
move to 920 and make image
..
..
..
move to 1100 and make image
This makes 20 steps but probably 10 steps or even less will do. The direction is not important. You could also do 1100 to 900. You should also be able to mix the test series. The detection doesn’t work above hfd=12 since it was designed for the alignment & solver and not finding the focus point.
