Ha Added The Hummingbird Galaxy In Canes Venatici (NGC4656,NGC4657)
A.K.A The Hockey Stick Galaxy

The Hummingbird Galaxy (Hockey Stick Galaxy) in Canes Venatici

I've added a significant amount of Ha and Lumi to the data I recently released.
I think it's finally in a decent balance.
Many images of this galaxy are taken in LRGB, but like its neighbor, the Whale Galaxy, I think Ha is a very important element.


りょうけん座にあるハミングバード銀河（ホッケー・スティック銀河）

先日公開したデータに新規にHaと全然足りなかったLumiを大幅に追加した。
やっとまともなバランスになったかな。
この銀河はLRGBで撮影されてるものが多いが、お隣の鯨銀河同様にHaがかなり大切な要素だと思う。
