RE: [guide-user] Catalogue B1.0

Pat, I'm sure that David Monet will assign to Bill one USNO-B.1.
So it will be our interest to ask him if he could make the same thing he
did with GSC-ACT.
I'm involved mainly in MP work and I don't agree at all with David about
the fact that it is not so useful for "normal" work.
I have actually 1 120 Gb HD on my PC, where I have ALL USNO-A.2, GUIDE8,
GSC-ACT, The Sky 4 and RealSky permanently loaded. I'm ready to buy a
second HD of 80 Gb or more, in order to have the USNO-B.1 constantly available.
At 157 Frasso Sabino Observatory we are in your same situation, without
high speed connection to the web, so such a solution could be very pleasant.
I hope that there will be enough people, as non professional Observatories
involved in MP work, asking for such a facility.
I'm sure that like me everyone would be ready to pay at least the expenses
and postage to USNO or Bill, whoever.
Who agrees with me?
I think many people, so, Pat, wait a minute before burning 160 or 100 CDs,
may be this will be useless.
