Hi Mohamed,

If all the focus runs were done without changing filters and same star, looks really strange.

All reverse/no reversed should be the roughly the same values for -every- focus run and -not- be different by 2500+ steps difference between runs 1 and run 6

The '43' was actually the 2500 steps difference translated to stepper motor output shaft rotation difference in degrees betweens runs 1 and run 6.
