I'm not aware of any Vizier query limits. Disk space and bandwidth
may be practical limits in some cases, but I wouldn't expect them to
be a problem for 80 GB. (You meant GB, not Gb, didn't you?)

I've recently downloaded Simbad quasars using the Vizier query and
there was a 20,000 row download limit per each query. Given that
USNO-B has over a billion rows, that comes to 50,000 queries required.
I suspect that even you would find that to be a limit, Steve. :-)
