This does not happen all the time. It usually happens, when I disconnect the telescope in the ASIAIR App and slew to a new object with SkySafari 6 Pro on the MBP. Not all objects are visible in the ASIAIR SkyAtlas. Of course, I could use the search function... anyway ... When disconnecting SkySafari and reconnecting the mount with the ASIAIR App, I sometimes seem to have the issue after slewing of no star tracking.
Just noticed.... seems to be unrelated to SkySafari. I just slewed from Jupiter to a nearby star and back and there is no tracking grrrr...
