Leo Trio (M65, M66 and NGC3628) - v.2018
In this classic depiction of the three galaxies in the constellation Leo, I would like to once again be surprised by their diversity. As if specially they are visible from different angles. Thanks to the dark sky of the Rhodope, it was possible to see very weak sleeves and stellar tails of all three galaxies.
