Comments: I wanted to get a deep image of this mixture of open star cluster and reflection nebula. I’m satisfied with the result.

The Pleiades, also known as the Seven Sisters or M45, is an open star cluster containing middle-aged hot B-type stars located in the constellation Taurus. It is among the nearest star clusters to Earth and is the cluster most easy to see to the naked eye. It is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars is now known to be an unrelated dust cloud in the interstellar medium that the stars are currently passing through.
