Neil Booth Photo M45 Seven Sisters from Timperley

This is a photograph taken on Monday 3rd March 2014 by local Astro-photographer Neil Booth. 

M45 from Timperley before it went cloudy. Combined exposure time of 46 minutes. Should point out that it’s not cloud in the picture but blue reflection nebulosity from a cloud of dust passing infront of the cluster.

Technical details:

Total exposure time 46 minutes.
23×120 sec unguided subs, iso 800.
24×120 sec dark frames iso 800.
Aligned and stacked in Deep Sky Stacker and processed with digital photo professional.

In astronomy, the Pleiades, or Seven Sisters (Messier object 45 or M45), is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The celestial entity has several meanings in different cultures and traditions.

The cluster 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 was thought at first to be left over from the formation of the cluster (hence the alternate name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighbourhood.
