Astrophotography: The ultimate geek hobby

Eta Carinae

Perhaps the ultimate geek hobby, astrophotography combines a love of astronomy, artistic creativity, technology, and patience. The three photographers in this gallery have given their generous permission to use their images to illustrate what is possible when you devote yourself to this very cool hobby.

This image of Eta Carinae and the following 10 are courtesy of Chile resident Geert Vanhauwaert. (Technical notes are those of the photographers.) Geert's gear includes a C8 (Celestron) telescope with equatorial mount and a Canon 450 XSI camera. According to, Eta Carinae is one of the most massive stars in our galaxy, 8,000 light-years away, and the surrounding nebula is about 10 billion miles across.
