SOLVED: Autofocus with Esatto and C11

I have struggled with getting EKOS to autofocus with my Esatto and C11.  

I discovered that I needed a much larger initial step size than I had thought, which ended being an initial step size of 30,000!  The Esatto has 420,000 steps, so 30K is not has large as it seems.  I tested it with the Polynomial method and it achieved perfect focus in just 7 steps.  Repeatedly.  I was never able to get the Linear method to work, as it still stops at the wrong spot after calculating the correct one.  But the Polynomial works great.

So the advice that solved this problem was simply to manually achieve perfect focus, measure the HFR, and then see how many steps it takes to get an HFR values 3 or 4 times higher.  With the Esatto, that turned out to be 30,000.

Thanks very much for your findings, that's great!

I will hopefully be able to give it a try with your recommended settings whenever the clouds roll out, i.e. by the end of the week.
