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.
