Both enclose together approx. 700 stars, often blue ones with more than 5000-fold brightness of the sun. Because of bad conditions (clouds, very high air humidity, clarification) only one single exposure.

This cluster from stars in the constellation Kneeling Man contain about 500,000 stars on the narrowest space. M13 has a diameter of 175 light years and is approx. 23000 light years away.

What one can see only on a longer exposed photo, is the blue shining Reflectionnebula. They exist from the interstellar dust which reflects the light of the stars. Approx. 500 of them belong to this star cluster, nevertheless, they stand far apart. The light of this star cluster is on the move approx. 400 years to us.

There are many well known Deepskyobjects to discover, like, among the rest, the horse head nebula B33 / IC434, the big Orionnebula M42, and in the middle of the picture the gigantic hydrogen complex "Barnard's loop", which stretches through the whole constellation. On the top left you can see the Rosette nebula NGC2237.
