Sagittarius Milky Way
Sagittarius Milky Way At midnight in the middle of June, at around 12:00 pm, you can see the Milky Way in summer, and We can see it with your naked eye, binoculars, and telescope. When you look at something that looks white with a telescope, it looks like a star and you will never get tired of watching it.

Reflector test
2020-06-16 Foucault test image of 45cm F/4 reflector. This mirror is a sandwich mirror from Habble optics. A friend tested it when I removed the mirror to change the cell. There is a small hole in the middle of the mirror, but it seems to be overcorrected overall. I found that it can be used for F/4 planets.

Mizuki beach
2020-05-14 Mizuki beach, Ibaraki prefecture. I went out to watch C / 2020 F8 Swan, but I could not check the comet! The sight of the horizon of the sunrise and the moonlight reflected by the waves is beautiful!

Moonlit milky way
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.

Cleaning the telescope
I cleaned and adjusted my own 45cm Newton reflector telescope. It can be done by one person, but it was finished smoothly with the support of my friend, Mr. Ishii. The drawback is that the optical axis tends to go wrong, but it is unavoidable that adjustments at each meeting are made by myself!

Atlas Comet
2020-04-25 omet/2019 Y4 Atlas Imaged at Nasu Observatory (40 cm Cassegrain). There was a thin cloud, but I got a subsequent image of the fragmented comet. With a large concentrating power of 40 cm, I could watch it!

The Nasu Observatory
2020-04-25 I have observed at the Nasu Observatory. It is a private observatory owned by Mr. Sugimoto of Utsunomiya City. Professional high-precision 40 cm Cassegrain and equipment for all observations are on a large fork equatorial mount. It’s a big equatorial mount, but it’s amazing how easy it is to handle!In the daytime, I enjoyed the Hα image with the solar telescope. Thank you very much.
