The Great Sagittarius Cluster (射手座の大球状星団) Messier 22

Looking at the All Sky Camera, the sky above the observatory had cleared up near sunset. All the CSky members were excited.
Looking at the movement of the clouds over the satellite, it looked like we'd be able to shoot for about an hour after sunset. I hadn't seen the stars for two whole months so I was 200% stressed. I prepared to shoot for even an hour. In the end I was only able to shoot for 30 minutes.
Anyway, I wanted to see stars filling up the screen, so I targeted M22, a globular cluster in the Milky Way.
I emphasized the entire star, so it looked more like a dense part of the starry sky than a globular cluster, but I was happy because I'd achieved my goal of filling up the screen with stars.
The stars are green, probably due to the thin clouds.

All Sky Cameraを見ると日没近くから観測所の空が晴れていた。CSkyのメンバーもみんなソワソワしていた。

サテライトの雲の流れを見ると日没後に1時間くらいは撮影できそうな感じ。まる2ヶ月星を見ていないのでストレスは200％。1時間でもいいから撮影しようと準備。結果30分だけ撮影できた。

兎も角画面いっぱいの星が見たかったので天の川にある球状星団のM22をターゲットにした。

星全体を強調したので球状星団というより星の濃い部分みたいな表現になったが、目的の画面いっぱいの星は達成できたので良しとした。

薄雲の影響か星が緑だな。
