Observing the galaxy NGC5962 in Serpers


Hi all, yesterday night the sky was very clear in my location in Germany. The star "19 Ursa Minoris" in the north with a brightness of 5.48 magnitudes was clearly visible with the naked eye from my roof observatory. I decided to cool down my compact 21cm dall kirkham cassegrain telescope to go for galaxy search. Yes, the spiral galaxy NGC5962 in Serpens with an apparent size of 2,5"x1,6" and a brightness of 11,44 magnitudes was indirectly visible(!) throught my telescope. This is the faintest galaxy I have ever observed with the Mewlon from my roof observatory! I used a "Baader Moonlight and Skyglow" filter to eliminate the heavy light pollution coming from BK-City in the east..

Observing the planetary nebula NGC4563

On April, 8th 2010 I observed the CatEye planetary nebula in Draco using my 21cm DK telescope. Althought it is quite small, I observed at 300x some structures inside this nebula. This has been confirmed with my test photo below:
At a 60x magnification, I could also observe the galaxy NGC6503 (10,2mag) in Draco. It was like ax quite small cigar but it was still observable even from my light poluted site. That didn't happen with its fainter "neighbour" galaxy NGC6654 (11,84mag).

Together again: Venus and Mercury



Both inner planets of our solar system are visible these weeks in the west after the sunset. Their best approach will be on April 5th, 2010. Don't miss it! This photo is taken from my observatory in Germany using an old Nikon Coolpix 4500 (4 seconds at ISO400).
