Messier 45, sometimes called Seven Sisters, Pleiades, or Subaru, is an open cluster located in the constellation Taurus. The cluster contains many hot blue stars and it’s characterized by reflection nebulosity. The cluster is easily visible to the naked eye and therefore it has been used in the mythology of many cultures around the world.

The picture was created by stacking 80 pictures with a total integration time of 4 hours. In order to capture the nebulosity properly, the light pollution should be minimal, which I manage to experience during our trip to Milos Island. Unfortunately, the mount was not cooperating and in the declination axis occurred oscillations due to backlash. Therefore the stars are a bit oval. Maybe it’s time to upgrade the mount and pick something backlash-free. I would select something portable like Astrotrac 360 or Avalon Instruments M-Zero.
