I down loaded it to Guide 9.0 and now I have more stars on my star
charts than I can see in my Telescope.

Subject: [sac-forum] UCAC4 all-sky star catalog
USNO published their latest all-sky star catalog, UCAC4, last year.
This catalog is complete to 16th magnitude and features much better
positional and proper motion data than its predecessors. It is gradually
being integrated into many planetarium programs. If you have a program which
can reference the catalog data, and are interested in obtaining a copy of
the catalog files, you can request a DVD from the Naval Observatory or
download the files from a CDS (Centre de Données astronomiques de
Strasbourg) mirror. The 900 data files in the catalog, combined with a few
dozen support files, occupy 8.5 GB, so the download option takes a while. It
took me most of the weekend, but I was able to grab the full set and can
make them available in a ZIP file (only 5.5 GB
:-) on USB flash if you want to get a copy from me. I'll bring the flash
with me to AAMM next week and again to the club meeting on the 22nd. I'm
hoping before then to have signatures (hashes) of the files from USNO to
ensure that none of the data are corrupted. It only takes a few minutes to
copy the ZIP file from the flash.
If you're interested in copying my data prior to the AAMM, contact me off
list and we can make arrangements to meet up somewhere convenient.
It's not like I'll be out observing over the weekend as I'd planned :-(.
