slight bump after 3 Mo.
the above link looks dead so...
as one of the map makers and add on creators
( shameless plug for me and the others)
it IS RECOMMEND that you ( the person reading this) use the SVN pull of the "soon to be" Celestia 1.7
QT4 is now used for the GUI
svn co https://celestia.svn.sourceforge.net/svnroot/celestia celestia
and on a working copy build it
autoreconf -v -i
./configure --prefix=/usr --with-lua --with-qt --with-cspice-dir=/opt/cspice
for those who USE "qt creator" there is a 'celestia.pro' file
and check out the very high resolution planet Venus add on for a look under the clouds
