This is great software, for budding professionals and keen amateurs alike.

But I've got to say, this is now what, 10 or 11 years old? And it still hasn't reached a 1.0 build number? Gotta love open source software

Wonderful conjunction of 1st crescent moon, Venus and Jupiter this weekend makes me want to install this and explore. Mars quite visible this season, too.
