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.   Peter
