The Propeller Galaxy (プロペラ銀河) NGC7479

new season start
新シーズンスタート

For the past three years, I have not been able to take any pictures in July, and although I declared the season off a few weeks ago, I have already been able to shoot for more than six days in July this year. This is more than February, which is the peak of the season this year.
Therefore, we decided to start the new season three months early.
When I wake up at 3 o'clock in the morning and look up at the sky, I can shoot. I made hasty preparations, and while the CCD was cooling down, I decided on a target that I could manage to capture in an hour.
Well, with the 540mm HS11, thanks to Fast, I could take good pictures of the faint parts around the Arm, but I couldn't get the detailed parts of the dark belt.
If I have a chance in the future, I would like to shoot at 2000mm.

この3年間は7月は一切写真が撮れなく、数週間前にシーズンオフ宣言をしたが、今年は7月に既に6日以上撮影ができている。これは今年のシーズンピークの2月よりも多い。
よって3ヶ月も早めであるが新シーズンをスタートすることにした。
深夜3時に起きて空を見上げると、撮影可能。速攻で準備をして、CCDを冷却している間に1時間でなんとか撮れそうなTargetを決めた。
うーん540mmのHS11だとFastのおかげでArm周辺の薄い部分はよく撮れるが、さすがに暗黒帯の詳細な部分は出せなかった。
将来チャンスがあれば2000mmで撮ってみたいな。
