Tonight I again spent the night at the Tacande Observatory on La Palma. There we observed the Coma galaxy cluster. The result is this photo taken with a modified EOS6D camera.

For post-processing I used the free software DeepSkyStacker and GIMP. The full resolution images is available here.

Clear skies!

Star cluster Messier 44

Tonight was the first time since mid of November with acceptable conditions for astropohotography… I don’t like this weather… However, this night it was good – at least until about 3am. For stacking I again used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. Happy Easter! 🙂

Fireworks Galaxy (NGC6946) and open cluster (NGC6939) in constellation Cepheus

Fireworks galaxy (NGC6946) and Open Cluster NGC6939 - 2015/08/11

This is a photo taken from a less popular region in constellation Cepheus. On the bottom right is the spiral galaxy NGC6946 also known as Fireworks Galaxy. On the top left is an open cluster with the great name NGC6939. The seeing was ok but could have been better… like most of the time 🙂 For more details on the equipment take a look at the equipment page. For stacking the images I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping.

Imaging the Cocoon Nebula (IC5146)

Cocoon Nebula (IC5146) - 2015/07/21

Tonight I imaged the Cocoon Nebula (IC5146) – a reflection / emission nebula in constellation Cygnus. The cluster is about 4,000 ly away. The seeing was great and the guiding with PHD worked perfectly well. I was a fantastic summer night.

For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. The picture is also available in full resolution here.

NGC6914 – The dark monster of Cygnus

/ Carsten / Leave a comment
Emission nebula NGC6941 - 2015/07/15

Behind the unspectacular name NGC6914 a nice emission nebula in constellation Cygnus is hiding. To me the nebula looks a little like a dark monster with two deep blue eyes in the center of the picture 😀

The picture is also available in full resolution here.
