Hello,

I just today found
  https://fedoraproject.org/wiki/SIGs/Astronomy
  https://fedorahosted.org/astronomy/

and thought the following project might be of interest to you:

My Linux4AstronomyF11DVD Sourcforge Page
  http://linux4astronomy.sourceforge.net/
  http://sourceforge.net/projects/linux4astronomy/
FILES & INFORMATION
  http://sourceforge.net/projects/linux4astronomy/files/Linux4AstronomyF11DVD/

This is indeed a customized LiveCD bootable DVD I created with many astronomy packages on it, including imaging software, stackers, image editors, Kstars and others.
Also supports long exposure modifications for Philips webcams, but supports many webcams.
