Imaging the Cocoon Nebula (IC5146)

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

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 😀

Astrophotography Oberstdorf – Imaging the Witch’s Broom Nebula

This article is about Astrophotography in Oberstdorf. Last year I put all my equipment into the car and drove to Lake Garda. Unfortunately, in contrast to the forecast I had lots of clouds and no chance to take a good astro-picture. Last weekend I decided to give it another try and took all my equipment to Oberstdorf – a small village at the foot of the German Alps. Beside hiking I think this place is well suited for astrophotography.

I found a good place not far from the center of Oberstdorf, with free view to Polaris and almost no traffic:

GPS coordinates: 47°24’17.5″N 10°17’28.9″E

Important update: The described location can only be reached by car when driving into a “no entry” road. Of course you do this on your own risk.

(Oh, and btw. a good Italian restaurant is also not too far: Ai Quattro Canti…)

Imaging the black claw of Vulpecula – vdB126

vdB 126 is a reflection nebula in constellation Vulpecula. To me it looks like a black claw with at least 4 fingers.

I like the many stars in this region! In this clear night I was able to get 8 good IR frames before the moon rose. For stacking I used DeepSkyStacker 3.3.2 with Kappa-Sigma Clipping. The picture is also available in full resolution here. Finally, I decided to put it into my My Top Astro-Pics gallery.

Astrohotography of Sh2-88 without H-alpha filter from Böblingen / Germany

The evening of 24th June 2015 was a warm and nice summer evening. All the clouds vanished and the forecast predicted a clear night 🙂 Since I didn’t image a nebula for quite some time I decided to image one this night. Recently I came across Sh2-88 which is an HII emission nebula in constellation Vulpecula. So this should have been the target for tonight!

I saw some great pictures of Sh2-88 before which have been taken using an H-alpha filter. Since I am not yet having an H-alpha filter I just decided to give it a try without H-alpha. Of course the nebula structures don’t come out as good as when using a such a filter. But I am still satisfied for a picture with just 5 IR frames. The seeing with my f/5 GSO Newton (F=1000mm) was around 2.1″ – so quite good for this region.
