Pleiades or Seven Sisters - M45
An open star cluster containing middle-aged, hot B-Type stars located in the constellation of Taurus. The cluster is dominated by extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster. The dust extends throughout this image. Comet C/2015 ER61 is in the upper right from M45. Taken with a Ha Modified Canon 6D and 200mm f/2.8 lens at f/2.8 - uncropped. In all 55ea 45 seconds exposures. Processed with PixInsight.
