M45 The Pleiades Cluster
M45 or commonly known as Pleaides is arguably one of the prettiest Messier objects. The Pleiades are also mythologically known as the Seven Sisters: Sterope, Merope, Electra, Maia, Taygeta, Celaeno, and Alcyone. Their parents are the stars Atlas and Pleione. The Subaru is the Japanese name for the Pleiades or the "Seven Sisters" (one of whom tradition says is invisible – hence only six stars in the Subaru logo), which in turn inspired the logo
The Pleiades might look like a constellation; however, it is an asterism. An asterism is a commonly recognized group or pattern of stars that is not a constellation. The Pleiades are very easy to spot with the naked eye. The Pleiades can be seen easily even in a very light polluted Bortle 9 sky.
The best way to find Pleaides is by finding Orion’s belt and following the belt up to Aldebaran and then follow that line to a small cluster of stars. You have arrived at Pleiades.
Pleiades is an open cluster of stars and it’s a reflection nebula formed at a young age of 100 million years ago. Pleiades is about 391 million light-years away. The blue nebulosity around the cluster is made from dust particles reflected off the light from the nearby stars.
This is another picture I wish I had taken more subs of. This is a 30-minute unguided shot. These are fifteen, two-minute images stacked together. This is another target that I will have to re-acquire now that I have a better mount and a better understanding of Astrophotography
