This is a multi image stack all taken with my TMB-130 apo refractor, the modified Canon 6D and an IDAS LPS-V4 filter. Images were stacked and calibrated in Registax and processed in Photoshop CS6. Cumulative exposure was about 15 minutes at ISO 3200-6400.

The Pleiades

"The Pleiades (/ˈplaɪ.ədiːz/ or /ˈpliː.ədiːz/), 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 neighborhood."
