1)
In SkySafari 6 pro, stars fainter than 13.0mag are no longer included, except variable stars, which go down past 15mag. On June 16, everything was ok, so it happened at sometime between now and then. I'm not sure if I had the latest version of SS6 on June 16. The Screenshots show M37, the faintest non variable star is at 12.3m, although stars down to 15m should be visible at that zoom.

After de- and reinstallation, the stars are still missing. Moreover, all my observations are gone, although they are visible on LiveSky. This happens every time I deinstall SS6.
