John, yes CdC == Cartes du Ciel == Skycharts. It's free and how big it is depends on what catalogs you add to it. The base Win32 download is about 30MB. The supplied DSO images add 57MB and the extra stars 52MB. I also have compiled copies of NOMAD (~210GB but compresses to about 97GB), UCAC3 (~4GB) and UCAC4 (~6GB). I could cut you a couple of DVDs of the version of CdC I'm running, the extra DSOs and stars, and compiled UCAC4.
The jpg and zipped CSV are roughly the area you asked about, restricted to mag 14.4 (Extended Hiparchos, Tycho-2, GCVS, and SAO catalogs).
