Total exposure~2h40m

End of February 2014 I already recorded M101 from Boeblingen near Stuttgart. The total exposure time was about 6 hours (!). This time I did a 2h40m exposure from Los Llanos de Aridane on La Plama with exactly the same equipment. This is the result.

From my perspective the two pictures do not have a big difference despite the colour tone which of course depends on the post processing. However, it’s interesting to compare the results with respect to their total exposure time: The image recorded from Boeblingen was exposed more than two times longer.

As a result of the long exposure time the stars are not as perfectly round as the ones with a shorter exposure time. Despite that I am happy to see what is still possible from a city like Boeblingen 🙂

Finally I combined both images to one final image by rotating one image until it matched exactly. Maybe I am wrong but I think in the end this combined image has a little more detail than each of the pictures alone.

A full resolution image is available here.

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 – Taking a look at spiral galaxy “Messier 100”

In a clear night I recorded this image of “Messier 100” – a spiral galaxy located within the southern part of constellation Coma Berenices – from Los Llanos de Aridane on La Palma. It is an LRGB composite consisting of 11 luminance frames a 600 seconds and 9 red, green and blue frames a 150 seconds respectively. The image is also available in full resolution. The seeing conditions tonight were perfect (seeing ~1.95″) and there was no local wind. The annotated image shows a lot of other interesting objects like NGC4323, IC783, NGC4312 and NGC4328 beside M100. Some objects I was not able to assign, yet – those are marked with question marks and could be additional galaxies.


First Astro-Tour on La Palma with own equipment

Well… I like the moon… but… YEAH! He is gone! Time for astrophotography, again! 🙂 For this purpose I rent a VW Caddy here on La Palma. The plan: Put all the equipment and my girlfriend into the Caddy and drive up to Mirador del Jable – a quite popular place for watching the stars.

One last look at the weather forecast from aemet… Looks quite promising! Even though it is almost impossible to predict the weather on La Palma. Furthermore, hdmeteo can be helpful to get an idea of the current weather conditions on the island. And last but not least the NOT webcam can give another impression. The decision has been made – tonight will be an astro-night!

The Great Orion Nebula from La Palma!

Recently I took this image of the Great Orion Nebula from La Palma / Spain. Actually it was just a test of my equipment. I did not align the mount and hence the guiding was miserable. I only took some frames with the IR filter with different exposure times. Still, in the end the result was much better than I expected. I love the La Palma sky!! 🙂
