Hi Bill,

after having downloaded and installed the test version of G9 and toggled the UCAC4 catalog which I have on my hard drive, another time hitting Alt J and inputting 12 does not bring me back to GSC numbers.
I still see the UCAC4/2MASS indentifiers of the stars. Sometimes if I do "next" in the popup window I get also other identifiers but not GSC numbers.
Maybe I could input the UCAC4 numbers Guide 9 tells me into VIZIER to find info in other catalogues, but going back to GSC would be still desirable in my case.

Thankls for the help.

Regards,

Josch
