2020-05-07 午前2時過ぎに起きたら晴れて出した。月が西にあったが透明度が良かったので天の川が薄っすら見えた。木星を見たが酷い気流で諦めた。45㎝ニュートンのスケアリングを調整したのでＭ22を試写撮像。望遠鏡では星がダンスし酷い気流が分かる。45cm F4,ISO6400,露出時間が2秒は月光の明るさ。2秒露出の50回の連続撮像はホント楽です。撮影機材の進歩ですね！ スケアリングはOKでした。星は大きいのは気流です。
2020-05-07 When I woke up after 2:00 am, it went out fine. The moon was in the west, but the transparency was so good that I could watch Milky Way thinly. I checked Jupiter, but gave up with a terrible seeing condition. I adjusted the 45cm Newton’s squaring, so I took a picture of the M22. With the telescope, the stars dance and I can watch the terribleseeing condition. 45cm F4 newtonian, ISO6400, exposure time 2 seconds is the brightness of moonlight. 50 consecutive shots with a 2 second exposure is really easy. It’s a progress in photography equipment! Scaring was OK. The big thing about the stars is poor seeing condition.
