What on earth gave you that idea? They simply *started* in the S Hemisphere and worked their way N...
For general stuff down to ~mag 16 UCAC will be the catalogue of choice. Scheduled for release later this year. FWIW UCAC1 and 2 were *interim* releases. Other than that it's USNO B1.0. So, for general stuff, the catalogues of choice will be... Tycho 2 -> Mag 11 UCAC -> mag 16.5 USNO B1.0 -> mag 20? Obviously there is a place for specialty catalogues. And in that case it's whatever floats your boat. And don't winge about crap astrometric and photometic data.

I'm seeing more stars in my C11 than the Tycho-2 catalog contains. There is the GSC-ACT catalog but its homepage on projectpluto says it's obsolete. USNO is nice but huge and I don't need mag-20 (I wish :). UCAC-2 sounds promising and contains the range of stars I care about. If I'm reading http://ad.usno.navy.mil/ucac/ correctly it's mostly geared towards the Southern hemisphere though, right? So, which catalog do you recommend for dim stars in CdC? Thanks, Sander Yahoo!
