There are a couple of ways of getting Guide to read RealSky (and/or
DSS) data from the hard drive, but I think most people will like the
method I've just documented at

http://www.projectpluto.com/faq_curr.htm#rs_on_hd

That should at least get things working... but the "better" way would
be for Guide to allow you to type in the path to the RealSky data, and
then have it _remember_ that path the next time you ask for RS images.
(Right now, you have to set a file to be read-only, which is very
user-unfriendly.)
