If I can get auto focus to work reliably and repeatably on my SCT I am keen for that as it does change focus significantly with temperature changes. Even just having it make automated changes between subs based on a measured temp coefficient will get me better data.
I have used the focus motor for one night on the SCT and even for manually focusing I am sold on it. I am pretty firm on the idea that the less you physically touch the rig in operation the better.
