Hi

I have downloaded the complete UCAC4 folder. However I can't seem to load it up under the Options menu as shown below. Catalogue 2 does not have a drop down for UCAC4. I have put in the folder details, but not able to pick UCAC4 in the drop down list as it's not there.

Anyone know what I might be doing wrong?

Regards
Andrew

Hi, the UCAC4 is a "Catalog 1". It cannot be used with GAIA2 at the same time.
"Catalogs 2" are usually on-line or slow catalogs, intended to extend "Catalogs 1".

Switching from UCAC4 to GAIA2 (as Catalogs 1) is fast because both folders are remembered.

Placing the UCAC4 also into the "Catalogs 2" is an interesting feature by the way, to obtain an even faster switch between them.

Clear skies,
Fabio.
