Herald-Bobroff chart references for the SAC database of deep-sky objects

The Saguaro Astronomy Club (SAC) Database is the result of more than 20 years of devotion to create and maintain a list of more than 10,000 worthwile deep-sky objects within reach of many amateur astronomers. The database is managed by Steve Coe and has a historic data format. It contains lots of information about these objects, such as the object type, celestial coordinates (RA and Dec), brightness, position angle etc. but also links to charts in the first release of Uranometria 2000.0 and in the Tirion Sky Atlas 2000.0.

Linux to the Rescue of Windows Vista

This weekend my parents bought a new Acer desktop that comes preloaded with Windows Vista. Upon first boot you have to choose the OS language. Usually from then on the setup works flawlessly. This time it didn't.

Some Vista users are caught forever in a reboot lock after undoing an OS update. In this case you can either be happy to have a Vista recovery DVDs at hand (which we obviously didn't have), or the only remaining option is a partition editor.
