I was able to record this image of three galaxies in a quite windy but clear night with my own equipment. This night I was based on a quiet place in Tacande on La Palma. I used my 8" GSO Newton telescope in combination with an Atik383L+ cooled camera. The optics were mounted on an EQ6 Syntrek mount. The total exposure time of the resulting image is about ~2h37m. It is a combination of 9 luminance frames a 600 seconds exposure time (binning 1x1) and 9 frames a 150 seconds exposure time (binning 2x2) for red, green and blue frames. A full resolution image is available here.
The three objects shown on the picture are M65, M66 and NGC3628 (also known as the Hamburger Galaxy). All are located in constellation Leo. M65 and M66 were discovered by Charles Messier in 1780. Both are intermediate spiral galaxies and between 35 million and 36 million light-years away. The Hamburger Galaxy is an unbarred spiral galaxy also about 35 million light-years away which was discovered 4 years later by William Herschel.

Imaging the emission nebula NGC6914 in constellation Cygnus from Böblingen / Germany

Behind the unspectacular name NGC6914 a nice emission nebula in constellation Cygnus is hidden. To me the nebula looks a little like a dark monster with two deep blue eyes 😀 The picture is also available in full resolution here.

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

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

Compared to Böblingen the light pollution in Oberstdorf is much less critical. I was even able to see the Milky Way from my observation point. The picture on the left I took this evening with my Fujifilm X-T1 camera (f/2.8, 15s, ISO2000). The image was saved as RAW and post-processed with rawtherapee. For this image the dark-frame subtraction was enabled. Unfortunately there is still some noise in the image.... :/

Anyhow, due to the good conditions Continue reading →

NGC2264 - Cone Nebula & Christmas Tree Cluster

Last night (2015/03/11) I surprisingly had clear sky here 🙂 I had no plan and finally decided to try imaging the region around NGC2264 before moon rise. The seeing was about ~2.5-3". This is the result:
