Hercules cluster of Galaxies, 450 MLY away

The image contains about 30 galaxies in Hercules cluster of galaxies. In the middle the NGC 6050/IC 1179 (Arp 272) is a remarkable collision between two spiral galaxies. The galaxy cluster is part of the Great Wall of clusters and superclusters, the largest known structure in the universe. Arp 272 is located some 450 million light-years away from Earth.
5 subs 900 sec, ISO 1600 with AP1200, C11 at f10, guided with Williams Optics APO 110 mm and NexImage videocamera.

Globular Cluster M92

The Globular Cluster Messier 92 in Hercules is a beautiful cluser not far from M13.
It is 27 kLY from the Earth and a nice target for astrophoto as well as visual observing. The image is taken with AP 1200 and C11, Canon 40D plus Williams Optics 110 mm Williams Optics and NexImage for guiding. The image is made of 42 subs with 90-120-240 sec at ISO 1600.

Supernova in galaxy M51

Earlier this summer, a Supernova appeared in the M51 galaxy in constallation Ursa Major.

The Supernova is show marked with a circle from a image taken 17 of September 2011. As comparison I have added a image I took in 2009 of the same galaxy.

Supernova in galaxy M101

24. of August this year, Oxford university astronomers discovered a Supernova called SN2011fe, in the Pinnwheel galaxy M101 in Ursa Minor. See the circle marker in the photo taken in 17 Sept 2009. The Supernova has brightened day by day since its discovery, quite astonishing! As comparison I have added the last picture I have taken of the galaxy in April 2009.

The Fireworks Galaxy NGC6946

The NGC6946 galaxy 1o MLY away between Cepheus and Cygnus is a spiral galaxy known to have had more than 10 Supernovas the last 100 years. As comparison, we believe the rate of Supernovas in the Milkyway is about 1-2 Supernovas every 100 year. But the last one was 400 years ago!
