Messier 35 cluster - 2015/02/19

Messier 35 or M35, also known as NGC 2168, is an open cluster of stars in the west of Gemini (left part of the image). To the right there is another open cluster named NGC 2158. Even if the two open clusters are “close” they are not related – their distance is about 9000 ly.

The image is also available in full resolution here.

Globular Cluster (M13) - 2014/06/25

Messier 13 (NGC 6205) is a globular cluster of several hundred thousand stars in the constellation Hercules. M13 is also known as Hercules Globular Cluster. Edmond Halley discovered it already in 1714. The globular cluster has an apparent magnitude of 5,8 mag and therefore is well suited for observation and astrophotography by amateur astronomers.

Beauty of space – My best astro-images in 2013

/ Carsten / Leave a comment

In this short video I summarized all the best astro images I made over the last year. Most of the images have been taken from Boeblingen using a 8″ Newtonian telescope and an Atik383L+ camera. All the images are also available in full resolution on my website. The video has been composed using openshot, an open source video editor for Linux (many thanks to the development team).

Clear skies!
