ASTRO: M13
This is sort of “first light” for my new Skywatcher Esprit 150ED scope. Actually it is second light, but the first night had such bad seeing that I could not get any useful data.
The sky was very hazy, probably because of sand from the Sahara desert that was blown over from Africa. M13 seemed a good choice under these conditions. Taken from the middle of Berlin with a Skywatcher Esprit 150ED at f/7 on a G11 mount, Trius SX694 camera, 12x2min L and 11x2min RGB each. http://ccd-astronomy.de/temp9/M13coloursharpgut.jpg Stefan |

Adding a large refractor to the collection. Looks like a good performer.
