Moon of 14
Moon of 14. One day before the full moon, the moon is almost circular, but if you look closely you can see a crater on the left side. It is too bright for a telescope.

C/2020 M3 ATLAS Comet
2020-10-31 01:50 (JST) The backlash after the mounting became severe, and adjustments were made. I took a picture of a comet in a bright moonlight night to confirm tracking. Did it recover because the sky in the back was bright and it couldn’t make a long exposure? I didn’t know, but I would like it to work even if it change the location to Cebu Island. You can see the tail in the upper right direction. The comet will move north in the future, and let’s take a picture again when there is no moon!

Mars October 30, 2020
Mars 2020-10-30 (UT) On a clear night, Seeing is too bad. I just recorded Mars images. Morning mist is remarkable around dawn, and it seems that pale clouds are spreading to the center.

Mars October 27, 2020
Mars 2020-10-27 (UT). Imaging cannot be continued due to the arrival of clouds. Seeing is also bad. On the surface of Mars, the morning mist (thin clouds) in the morning (left edge), the clouds on the north side (upper edge), and the western edge (evening mist) became conspicuous. The morning mist covers the Great Syrtis Major Planum and extends from the central Mare Tyrrhenum. The color of the feature is thin clouds and the colors are different. We can see thin blue clouds with a color camera, but you can clearly see them with RGB composition. A round white cloud can be seen to the south of the SPC in the morning

Mars October 26, 2020
Mars 2020-10-25 (UT) The transparency is a little poor, but I gave up because Seeing condition terrible. Difficult to adjust the color of Mars with a color camera We can observe the daily changes in the movement of clouds in the sky over the equatorial belt of Mars.

Mars October 25, 2020
Mars 2020-10-25 (UT) I dared to take a image of the poor seeing every night. The thin clouds in the sky above the UV image are doubled in the center, and you can see the contrast with the dark fairture in the B light image. Even so, it is a terrible poor seeing.

Mars October 20, 2020
Mars 2020-10-20 (UT) The transparency was good, but seeing was poor than expected, and the image of Mars is disappointing! The fairture of Mars was around 300 ° W, and Syrtis Major Planum, Sinus Meridian, and Hellas were visible. SPC is already small after summer. A pale cloud in the sky is always visible in UV images.

Constellation Direction
I used laser ponters to create the constellations. The green laser beam drew straight lines on the constellations in the night sky, and the image is quite, quite beautiful!

Sirius B
Sirius B 2020-10-18 Every autumn, I observe Sirius B (companion star). The main star, Sirius, is bright and it takes some getting used to seeing it with your own eyes. This time I found it at 200 x. If I used a 17 cm eccentric diaphragm as a test, the spider of the reflecting telescope would disappear and the star image would look like refractor, so I also found Sirius B. The point is to see it when the airflow is good!
