Jeff, just a couple of thoughts.
Are you using the time, date, position (Lat & Long) from your iPad to update that info in Explorestars? Anyway, however Explorestars is getting that info, double check it is correct. Especially the + or - for its position. Local time correct? The camera/vixen bar altitude is set to your latitude?
Do you have the mounts Home Position (north pointing tripod leg) oriented to True North, not magnetic North.
Wes has a great article in the files section of the Mounts Forum for establishing the mounts home position. It is geared for the iExos 100 mount, however I think its helpful for any mount.
