Tonight I decided to image the Trifid nebula (M20) which is quite "close" to the Lagoon nebula M8 from my last session. The seeing tonight was around ~2.4" which could have been better - but certainly it was still sufficient.
Back in 2013 I already imaged the Trifid nebula with the same equipment but from Boeblingen. It is interesting to see the difference here.
For post-processing I used the free software DeepSkyStacker and GIMP. The full resolution images is available here.

Clear skies!

Open Cluster Messier 46

This image of Messier 46 has also been taken at the Tacande Observatory in El Paso on La Palma. In fact this is a quite rare object in the sense that it is a star cluster with a planetary nebula. The nebula somehow looks like an eye in the nowhere of space. The image shown above is just an excerpt of the full frame. It is only one 4 minute shot with a modified EOS6D camera with ISO 800. The image is also available in full resolution here.

Astrophotography on La Palma - Messier 78

Last night I took my first astro-photo with my own equipment from La Palma. After quite some unsuccessful attempts in the past days and nights (because of some technical problems, strong wind and clouds) this was a very big moment for me, and I am proud to show my first result here 🙂 The image is also available in full resolution here. I decided to put this image into my "Top Astro-Pics Gallery".

The Cocoon Nebula (IC5146) - A reflection / emission nebula in constellation Cygnus

Tonight I imaged the Cocoon Nebula (IC5146) in the constellation Cygnus. The cluster is about 4,000 ly away. The picture is also available in full resolution here.
