When I connect my iEXOS-100 PMC-Eight mount to AAplus [1.8.3(9.12)] via USB, everything works except tracking. I can use PA to get alignment to <2.0 very easily, GOTO from catalog works perfectly, but the mount does not track. I have verified that tracking is turned on, and I have tried all tracking speeds and no tracking takes place. I have tried using the ES ExploreStars app, and tracking is spot-on over 5+ minutes at least, so I know that the mount is capable of tracking pretty well. I should mention that I am not using a guide scope with either program. I have also used StellarMate to control the mount, with results similar to ExploreStars. Is AAplus using the latest ASCOM drivers from Explore Scientific? Many thanks for any help!
