Hello Kent,
The problem was, as you suspected, that I wasn’t clearing the apps from running in the background the way you advised. As soon as I did this, everything started working like it should with ExploreStars. I’m going to try using SharpCap Pro for polar alignment which if done right may allow me to avoid doing a two or three star alignment.
I’m still try to get my head around how & when it is tracking, but suspect it will be clearer after working with the mount. Thanks again for your help.
Jed
