If you're using v2.7x, use the online resources (globe icon in upper right toolbar) to download small subfields of the USNO catalogs. These go to about mag 20. While it may be possbile to download the entire catalog from the vizier source, it would take a very long time. USNO-A2.0 is 6GB. USNO-B1.0 has twice as many stars, with more data on each (including proper motion for very acciurate positioning), so it's 80GB.
Vizier has recently made some minor format changes that have been causing problems for CdC. Currently, USNO-B works, but for USNO-A, use the ESO Skycat source. Since Patrick has been working on v3, I don't think he will fix these problems in v2.7x. Note there are limits on how large the field can be for this. -John --- On Thu, 10/2/08, Malcolm Saunders <[EMAIL PROTECTED]> wrote: > From: Malcolm Saunders <[EMAIL PROTECTED]> > Subject: [skychart-discussion] supplemental star catalogs > To: [email protected] > Date: Thursday, October 2, 2008, 11:57 PM > I've downloaded and installed the GSC-ACT catalog, and > it helps a lot, > but is there another star catalog that goes a bit deeper? > That > catalog stops with 15th magnitude, I think.
