Thanks Chris and Dave. This is the reason I asked; there are a lot of conflicting views. Interestingly, I finally had the opp to check my 8" EdgeHD tonight and actually *needed* reverse enabled to get the final movement of the focus travelling CCW ... go figure.
And I'm loath to play with it anymore tonight as my EdgeHD is guiding beautifully atm and the focus is spot on and holding yay! I will however look again tomorrow night to make sure I wasn't seeing things. Alex
