The Pleiades are an open Cluster of more than 800 stars located about 410 light-years from Earth in the constellation Taurus. Most skywatchers are familiar with the group, which is currently in our Eastern sky, from sunset on, just to the left (North) of a reclining Orion, and is best seen with slightly averted vision (https://en.wikipedia.org/wiki/Averted_vision). Also known as the "Seven Sisters" and Messier 45, the object derives its English name from Greek legend. The Pleiades are the seven daughters of the Titan god Atlas and the ocean nymph Pleione. During an ancient war, Atlas rebelled against Zeus, the king of the gods, who sentenced his foe to forever hold up the heavens on his shoulders. The sisters were so sad that Zeus allowed them a place in the sky in order to be close to their father. This image was taken from our deck with a Canon Eos 760D camera through a 135 mm lens a total of 110 3-second exposures at ISO 400. Despite the extreme light pollution, intermittent cloudy skies and hazy conditions, you can still see some of blue reflection nebulosity of the brightest stars in the cluster.
