M13 video 2022-03-10 Seeing condition is good, and I challenged the atmosphere of watching a movie (editing at 8x speed for 1s exposure and 16x speed for 3s exposure). Seeing is very stable for this season, and there is little movement of the image even in the video, so the sense of reality is not enough. 45 cm newtonian F / 4 Neptune C -II UV / IR cut
I watched the movie of Castor double star in Gemini, the difference between the aperture and the eccentric aperture. It is a movie of 45 cm and 16 cm (eccentric aperture). The position is advantageous near the zenith, but in winter-type weather, it is clearer to narrow down to 16 cm, which is a typical seeing in Japan. 2022-03-07
NGC4435 (upper right), NGC4438 (lower left) Virgo galaxy cluster. 2022-02-25 45cm newtonian 2m x 60 sheets (2 hours)
NGC3190 An exoplanet at the head of Leo. The center right is NGC3187 (S-shaped rod-shaped spiral galaxy) V grade / 13.4 45cm newtonian. 2022-02-23 The optical axis and guide were good, but seeing condition was poor and the details of the nebula were not shown.
NGC 2857 is a spiral galaxy of Ursa Major, V magnitude / 12.27 You can see many galaxies around. 45cm F / 4 newtonian 2022-02-22
Sirius’s companion star 2022-02-12 Sirius B because seeing was a little better. It seems that the optical axis was slightly off. I know the video image well. It could not be confirmed visually.
NGC2818 2022-02-12 A planetary nebula at a low altitude (declination-37 °) in Pyxis. It was a bright condition in the southern sky of the moonlight, but the transparency was good and I could barely catch it. A small, dark planetary nebula, no details visible. ｍ＝ 12.5. 45 cm F / 4 Newtonian Neptune-C II UV / IR cut 2 x 2 binning 5s x 300 frame
I tried mosaic software that makes the entire feature of the moon. I hadn’t used it until now, but Photoshop’s Photomerge can easily synthesize mosaics, and it can be very useful on the moon! Why is it used? I regret it, but I will do my best from now!
