Sounds like a very interesting addition to the hand controller features. The question I have is whether it is a download upgrade to the existing controller or only available on a brand new hand controller. The reason I ask is because I have both a AP 900 and new AP 1100 mount. I have only one hand controller which is swapped between mounts (one is permanent setup and other mount goes to star parties). I have though about getting a second hand controller but have been holding out for a few years to see if there will be a completely new version. The one I have now has all the current updates installed.
I know that I can run the mounts from my computer when imaging and I do that....but sometimes I prefer the hand controller for fast visual observing.
