The Group Image Catalogue contains images from my own observatory along with those from friends, placed side by side for comparison. It is the hope that this helps people see the different image scales and results that can be acheived from different equipment. Each image can be clicked on to see the full image on Flickr and the camera type can then be seen which also effects the resulting Field of View.

The Hercules Cluster (Abell 2151) is a cluster of about 200 galaxies some 500 million light-yearsdistant in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies. The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure,
The cluster's brightest member is the giant elliptical galaxy NGC 6041,

From Wikipedia, the free encyclopedia:
NGC 4861, also known as Arp 266, is a galaxy in the constellation Canes Venatici. It was discovered by William Herschel on May 1, 1785.
Morphological classification of NGC 4861 has proved relatively difficult. Its mass, size, and rotational velocity are consistent with it being a spiral galaxy. However, due to its highly irregular shape, it may also be classified as a dwarf irregular galaxy. In fact, since dwarf galaxies are less massive and have lower gravitational potentials, gases and other material for star formation can move within them much faster, causing the galaxy to become a specific type of starburst galaxy, called a blue compact dwarf galaxy. It has also been described as a "comet-like" galaxy due to its resemblance to a comet.
