OBJECT DESCRIPTION

The Pleiades are one of the most beautiful open cluster in the sky. It can be seen even from polluted skies with the naked eyes. It is a good target for binoculars. The main six members could be distinguished in rural skies, however the cluster has 3000 stars.

The blue colored nebula reflects the light of the bright stars which has the same spectra of the stars. The clouds are conformed by dust molecular particles and it can be seeing because it has a different radial velocity
