Description Christian Cernuschi 2005-10-18 12:16:13 UTC

Version:            (using KDE KDE 3.4.1)
Installed from:    Gentoo Packages

If you point to m81,m82,ngc3077 you see that m81,m82 have wrong Horizontal orientation. They should be flipped H.

I realized that looking at a real photo and kstars map.

Thank You
