ASTRO: NGC 7814 annotated Retry
Missed most servers so trying again.
Rick The field contains many distant galaxies, most of which are well over a billion light years distant. This image sets a record for the most distant object I know I imaged. Since I don't check all images for distant objects I may have a more distant one in some other image but this is the most distant one I've found at 11.6 billion light years. Thus we are looking back in time to when the universe was only about 2 billion years old. Few quasars are known even further back in the past. Most didn't come into existence until several more billion years passed in the evolution of our galaxy. It's a real fossil. Here is a list of the objects I was able to identify in this image listed from right to left. This data comes in Right Ascension order and in my images with north up that runs from right to left. I didn't bother to reverse the list. All data comes from the NED database. If distance and magnitude were listed I included it. All are galaxies unless labeled QSO. BLY stands for billion light years. The magnitude is the last number. SDSS J000338.94+160220.6 is a rather odd double object. It seems to consists of both an elliptical galaxy and a star like object (the QSO?) below it that has a long slightly curving tail going to the left (east). I can't find anything on it. Sure is an odd object.

Nice hit Rick...
