Messier 35 in winter Milkyway. First shot with my new Skywatcher Star Adventurer travel mount. It works like a charm.

Shot with 50mm@f/2 Canon EOS 1000Da (modifiied without IR filter)

Small excursion yesterday night to the Odenwald. Here is the outcome. Very wet night. I had to dry the lens several times even than I used a dew cap. :-(

This is M13 the "Great Hercules Cluster". A globular cluster orbiting the center of our galaxy. I wanted to take photos of the Andromeda Galaxy as well but my laptop battery ran out of power before.... :-(

My rig:
- Carbon tube TS ED refractor 70mm f/6
- Canon EOS 1000Da (infrared filter removed)
- Finder telescope as a guide scope with a webcam (colour chip replaced with a high sensitivity monochrome chip)
- Celestron AS-GT mount

Globular Cluster M13 - 20130816

Messier 13 (M13), also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of about 300,000 stars in the constellation of Hercules.
M13 is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable star V11 with an apparent magnitude of 11.95. M13 is 25,100 light-years away from Earth. (Wikipedia)

I have submitted a request to the Bradford Robotic Telescope a few weeks ago. Now I got the result. A nice shot of M13 in Hercules.
