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.

 

This photo is the result of cooperation with my friends and colleagues: Vasily Oleynik, Edvard Povovich, Igor Dulevich.

 

This picture was photographed during January 2018 in Rozhen observatory, Bulgaria.
