Venus January 3, 2022

Venus 2022-01-03. The sky is blue with good clearness and good transparency. This time Venus’s inner conjunction is January 9th. Today, thin Venus floated in the blue of the background and was sharp. From now on, Venus will approach the Sun more and more, and there is a danger that the Sun will enter the tube of the telescope, so caution is required.

Venus Occultation November 8, 2021

Venus Occultation 2021-11-08 I was worried about the weather, but the weather was better than I expected and I could watch it from the beginning to the end. Compared to the moon in the blue sky where there is no contrast, was Venus brighter and seeing was better in the scene where the moon edge appeared hidden? I felt the perspective of the two celestial bodies. It was a mini-observation session while talking with Ms. Masiko, a star friend

Jupiter and Saturn are conjunction (December 15-23, 9 days)

Those are an image summarizing the progress of the approach between Jupiter and Saturn (December 15-23, 9 days). It fixed and edited Jupiter so that you can see the daily movement. The daily movement, changes in the distance between Jupiter and Saturn, and the accompanying changes in the relative positions and angles of the satellites. It was a wonderful planetary phenomenon that the two planets approached each other, approached each other on 22.23th, and passed each other.

Uranus September 8, 2020

45cm Newtonian reflection. The brightness of Uranus is about magnitude 6. In the 45cm aperture, Uranus appears to be a beautiful light blue disk even at 400x magnification. It’s a pity that the internal pattern is not visible. The reason the color and IR images aren’t beautiful disc images is because the optical axes are not perfectly aligned!

Both are bright and visible, but the beauty is surprising when viewed with a telescope. Saturn with a ring in particular.There is a mysterious beauty.
