Just received my Eaf. Everything seems fine, but I have a question about the backlash. Followed some videos on Youtube, and they were anywhere from 60 -120 or more steps of backlash. I just checked mine and the fine focus knob on my Zenithstar Z61 moved at 30. I had my steps set to 10. This seems really low compared to all the videos I watched, does 30 sound reasonable to you? New to this so I don't have a clue.
