Jupiter May 13, 2021
Jupiter 2021-05-13(UT) There is fog and the contrast of Jupiter in the low sky is low, but seeing is a little good. On the surface of Jupiter, dark spots like protrusions of SEBs are connected and splendid. The whole SEB is pale. The area from EZc to NEB has a strong redness, and it is one belt in the UV image.

Add fan
At that time, the old C14 used on Cebu Island had a hole in the cell part of the butt and a 5 cm fan was embedded to take a picture of Jupiter. There are two in IN and one in OUT. This time, we will add two 8 cm square USB supply fans and a temperature sensor to the tip of the cylinder. Which is the best arrangement for the wind direction of the fans as a whole? I’m thinking, so please teach me!

Milky Way from Nasu
2021-05-10 From the teahouse parking lot at Mt Nasu PassIn the strong wind, I was shown M51 and M20 by my fellow star 51cm Dobsonian. The back of the M51 was dark, so I could clearly see the two arms and see the best nebula. The equatorial mount installed in a ridiculously strong wind was dangerous, but it was a wonderful Milky Way from Cygnus to Cygnus, which I could see after a long time. Probably since I saw it in Jododaira when I was young!Milky Way data 2021-05-10 24mm. 85mm 105mm, 300mmSony-α7s (IR modification) UV / IR cut ISO3200 20-30 seconds (3-10 images combined)

Jupiter May 7, 2021
Jupiter 2021-05-07 (UT). The sky this morning became less transparent due to the influence of yellow sand. Seeing is still bad. GRS can be seen in the center. In the infrared image of IR-1000, the depiction of the Arctic region is different, and you can see a little Polar food.

Saturn May 4, 2021
Saturn 2021-05-04 (UT). The tilt of the ring is small, and it looks like Saturn, but the image is poor!

Jupiter May 4, 2021
Jupiter 2021-05-04 (UT). I expected that the high pressure would move away from Japan and seeing condition would improve. There was a smooth seeing, but it improved a little. I want an altitude of plus 10 degrees of Jupiter! On Jupiter’s surface, the SEB in the Southern Hemisphere is light at this longitude, and the SEBs are slightly dark and sharp. “DE” is visible in the lower right on CH4. White spots of methane bright can be seen in the upper left. Europa of the satellite is passing through the center.

Seyfert’s Sextet
NGC6027 2021-05-03 Seyfert’s Sextet is a group of galaxies located about 190 million light-years away from Earth in the direction of Serpens. Seeing is poor and the small parts are out of focus. Brightness is 14-16 mag, a dark object. I want good seeing and a longer FL (3m)!

Jupiter 2021-05-03 (UT) On a clear night, Jupiter at dawn is stunned by the terrible poor seeing!
