Corona Borealis Supercluster
A recent article in a popular Astronomy Magazine prompted me to search out this supercluster.? You see, the image in the publication was taken with the Mount Palomar 200 inche telescope with film.? The sensitivity of amateur equipment has come a long way in the past few years.? I was very pleased with the results.? In the photograph below, four stars are visible. The remaining objects visible are galaxies. The average distance to these galaxies is estimated to be one billion light years.
