Corona Australis Nebula

Astrotrac/Polarie Posted on Sun, September 18, 2011 15:06:59

In the small constellation Corona Australis (Southern Crown) lies a 42 light-years away reflection nebula. It is the nearest region where new stars are formed. This nebula complex was photographed by me on August 3, 2011 at 23:30 UT. Afterwards, the positioning of this area could be better. Also visible is a Globulair starcluster called NGC 6723. Location: Hakos Guest Farm Namibia.

Comet C2010 X1 (Elenin) captured from Namibia!

Comets Posted on Sun, September 18, 2011 14:15:05

On July 31, 2011 around 20:34 UT I tried to capture Comet C2010 X1 (Elenin) with my Astrotrac mount and the Canon EOS 40D with a Canon EF 200mm f/2.8 telephotolens. I thought I had failed because of the bright zodiakal light. Afterwards I learned that I still have captured this small comet. He stands on two shots, one of which failed by a tracking error. That leaves one pictured of 60 seconds, right in the zodiacal light. The comet is at the right undercorner.
