Venus and Jupiter (March 16-17)I cannot use the controller of the 45㎝ reflector equatorial mount, and it is compatible with a personal computer, but it is very difficult to use.The dawn planet observation season has begun, but Seeing is terribly bad and we have to give up.
The Kunimi Star Party (Nasukarasuyama City, Tochigi Prefecture) began using the astronomical facilities at the Nagamine Visitor Center in Kunimi in 2015, and held an astronomical observatory four times a year to learn about the beauty of the stars. The facilities in the back of the mountain were far from the city and there were few general spectators, so from 2019 we changed the location to Karasuyama station square. Although it was a bright place with street lamps, children and parents in the neighborhood came to peep and regular customers came. However, in April 2020, the visitor center was decided to close, and the telescope at the facility could not be used. Our modest meeting has ended. It was a loose activity for 5 years, but thank you.
Jupiter Great Red Spot Changes from 1994-2019. These 25 years of Jupiter images have shifted from emulsion film photography to digital imaging and are up to the present. The shooting method and subsequent processing have changed completely, and the resolution of Jupiter images has been greatly improved. In addition to color images, images can be easily obtained on UV.IR CH4, and observation images have changed
. Jupiter Great Red Spot / Changes from 2001-2019. C8, C14, 32cm and 40cmNewtonian reflector. 2004-2014 taken on Cebu Island. GRS density change and size reduction can be easily understood!
The mirror was removed from the cylinder by cleaning the self-made 45cm reflector and changing the focus position. I can work alone, but with the help of the star friend, it went smoothly! Thank you.
2020-02-08 Fun astronomical chat. Reunited with Nagai’s house in Sano City for the first time in long time ago. Star friends also gathered, and the core astronomical story continued, I was energized and stimulated by my energetic astronomical activities.and it got excited until night.Sano ramen was also delicious. Thank you
Winter Astronomical Observatory2020-02-01 Nasukarasuyama City Station SquareI was able to see the moon, Venus and winter constellations in wonderful sunny conditions.The wind settled down and the moon surface X of the crescent moon was clearly visible, rather than severe cold. Thank you
M46 and NGC2438 are located in the winter Milky Way in Pup, but they are quite low and cannot be seen unless the transparency is good. Tonight’s NGC2438 (planetary nebula), which had good transparency, was found to be pink around the circumference by visual observation at 45 ° (180x). Seeing conition was poor.
2020-01-19 Dawn moon. I check Mars, but seeing was still bad and I gave up. There was a moon after a long time and I enjoyed it visually. Copernicus and Glavius are missing, and I observed the earth’s shining slightly before seeing it in the phase of the lower chord!The lunar image has a 45cm newtonian( stop to 17cm diameter eccentric diaphragm). It may be effective when sseing is bad.
