NGC 5985
Date: 6/28/14
Description: NGC 5985/Draco Group and so (quite reasonably) is located in the northern constellation Draco -- all within this single telescopic field of view spanning a little more than half the width of the full moon. While this grouping is far too small to be a galaxy cluster and has not been cataloged as a compact group, these galaxies all do lie roughly 100 million light-years from planet Earth. Not as well known as other tight groupings of galaxies, the contrast in visual appearance makes this triplet an attractive subject for astrophotographers. [Ref: WikiPedia]
