The Ruby Star with Blue Star (ルービー色の星と隣の青い星) 119Tau,120Tau

Ruby star in Taurus. The 1st magnitude star Aldebaran is also red, but this 119 Tau with the name RUBY is also brilliantly red.
The contrast of the blue star 120Tau right next to it is wonderful.
It's one of the few stellar photographs that can be taken at 2800mm.

牡牛座にあるルービー星。1等星のアルデバランも赤いが、RUBYの名を持つこの119Tauも見事に赤い。
すぐ隣にある青い星120Tauのコントラストは素晴らしい。
2800mmで撮影できる数少ない星野写真かな。
