Image Description:
This is a portion of Abell 2199, a rich cluster of galaxies in the constellation of Hercules. The largest galaxy in the center of the image is
NGC 6166 . Move your mouse over the above image to see annotations for just a small handful of the galaxies in this field, and then click on the image to get the full frame. There are an astounding number of galaxies in this field. A fellow imager once referred to one of my long exposures of a galaxy-rich region as the "Solomon Deep Field", a moniker I kinda dig. So, consider this part of the Solomon Deep Field Survey. <grin> The above is a full-resolution crop of the full-size frame. North is up.
