The Hydra Galaxy Cluster (うみへび座の銀河クラスタ) NGC 3312

My friend Fernando who lives in Rio told me about a galaxy cluster in the southern sky.
The contrast between the galaxy and the 5th magnitude star is beautiful and the target is typical of the southern sky.
I wish I could have brought out a little more galaxy blue.

Rioの友人Fernandoさんに教えていただいた南の空にある銀河クラスタ。
銀河と5等星のコントラストが綺麗で南天の空らしいTargetだ。
もう少し銀河の青を出せたら良かったな。
