Is it possible to calibrate manually the position of the filter wheel?
In my wheel the filters are not centered enough. Attached you will find my master flat. The camera es oriented in landscape mode and the filter wheel move the filters from right to left or viceversa. As you could see, it's a severe vignetting on the right side. If I move manually the filterwheel to the left I could obtaing a very good flat image as you could see on the second attached picture.
is there any way to adjust the calibration of the filter wheel via firmware, driver or physically?
