Object name: KING05
King 5 is an open cluster in Perseus. Being in the winter Milky Way it is in a rather rich star field. Not nearly as rich as the summer Milky Way however since we are no longer looking inward toward the core of our galaxy where most stars reside but more outward toward the suburbs so see fewer stars. Most stars in the Milky Way are small red dwarf stars. Most of the stars we see with the naked eye are giant stars and most of those are blue in color since those that are red are dying and won't be around very long. Though giant blue stars can be short-lived those that are only bluish last a few hundred million years so to make up the majority of the bright stars we see. This is seen in this image as well. The few bright stars are blue, most of the rest dim orange-red stars. Every red dwarf star ever created is still alive today unless it collided with another star -- extremely rare so its safe to say 99.9999% of all red dwarf stars are still around. Thus by sheer number, they dominate by number but not by light. Even their masses can't outshine the few massive blue giants that form the spiral arms of galaxies. Thus we see most spiral galaxy arms as somewhat blue in color even though that color is created by the smallest population of stars.
