New observing report with images: Pluto and Palomar 8 - 16/17 July 2013
Dec
4
In summer 2013 Pluto reached opposition on July 1st, 2013 in the constellation Sagittarius. I used an interval of 24 hours to capture the motion of the dwarf planet. Pluto shines at magnitude +14 from a distance of 4.7 billion kilometers from our home planet. Nice side effect: Palomar 8, a globular cluster can be seen 7 arcminutes nearby.


New observing report with images: Planets at sunset and double cluster
Nov

After a rainy day the evening sky became almost clear. The young crescent moon, a bright -4.0 mag Venus and Saturn were shining near the southwestern horizon.
Three hours later I tried to photograph the double cluster in Perseus. Clouds and fog interrupted the shooting.


New observing report with images: two PNs NGC 6905 and NGC 7026
Oct

There are many examples of excellent planetary nebulae images on the web. Using a test setup with the Celestron 11 and an ATIK 383L+ we took several 10 to 15 seconds single exposures of two planetary nebulae in Cygnus and Delphinus.


New deep sky image: M 17, Omega Nebula in Hα

During summer I tested my imaging setup and photographed the Omega Nebula Messier 17. The Omega Nebula is between 5000 and 6000 light-years from Earth and it spans some 15 light-years in diameter. The total mass of the Omega Nebula is an estimated 800 solar masses.

Deep sky image of Nov 2013: Messier 45, the Pleiades in Taurus
The Pleiades or Seven Sisters (Messier 45) is an open star cluster in the constellation Taurus. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Faint reflection nebulosity can be seen around the brightest stars. The exposure time was about 6.5 hours using a Takahashi FSQ106ED refractor @ f/5 and an ATIK 383L+.
