Hi guys,

Thanks for your replies.
Switching on the Star dispülay GSC does not help as already mentioned too much on the screen and only 4 of the 8 digits displayed.
Also only those stars with Tycho numbers are the same numbers for the GSC stars. Unfortunately there are many more GSC stars without Tycho numbers.
All worked fine before I switched to the new version and followed Bills way of getting UCAC4 numbers, but the way back to GSC numbers (hitting Alt J and inputting 12) did not work anymroe.

Regards,

Josch
