The Pleiades, or Seven Sisters (Messier object 45), 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.

Didn't get as much time as I would normally like on this object, primarily due to my body demanding sleep. I had to wait until the moon set at about 11pm before I could even start imaging. Need a lot more data on this to bring out all that faint dust. I messed up the framing of the cluster and as a result I may have missed one or two of the stars. It's a tight fit in my telescopes field of view. Tracking/polar allignment could also have been a bit better. On the plus side I have been trying to fix my double diffraction spike problem lately and I think I have finally sorted out the issue. Still needs a minor adjustement or two but it is much better than what it has been.
