The Fireworks Galaxy (花火銀河) NGC6946

This galaxy is not M101 - the Fireworks Galaxy, but the Fireworks Galaxy in the constellation Cephas, north of the Summer Galaxy.
My goal was to see the main galaxy of this color piled high with Hii regions, but it got cloudy and the Ha Signal only got cut off halfway.
I feel like this galaxy is actually more completely shrouded in haze.
I'll try again.

この銀河はM101ー回転花火銀河では無く、夏の銀河の北にのケファウス座にある花火銀河。

目標はこの色合いの銀河本体にHii領域がてんこ盛りになっている姿だったが、曇ってしまいHaのSignalがが半分で終わってしまった。

本来この銀河はもっと全体に霞にまみれてる感じのような気がするな。
