M20 video 2022-03-10 (in twilight) Neptune C-II (2x2binning) 1s exposure. The back is a little bright, but you can see the dark structure of the M20’s three fissures and the red Hα region at the bottom left. The field of view is too small to fit in the whole.
M27 video 2022-03-10 The image of a 45 cm caliber is like a movie. I edited a video of 1 second exposure x 1100frames to a 24 frame rate. Even with the Neptune C II camera, the M27 is pale, so you can clearly see the shape of the outer shape with 2×2 binning, and the bluish star in the center is beautiful. The optical axis is slightly off due to the bending of the telescope tube
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
Sunspot 2022-03-09 We are still challenging the fine structure. It is a comparison with the size of the earth.
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
Dwarf Galaxy Leo I, II, III (Leo) I tried to compare and understand the three dark and pale objects. 45cm Newtonian ASI071MC Pro
Dwarf Galaxy Leo III, Leo A (Leo) I think this object near the zenith is the lightest of all the objects so far. There are many galaxies in the HST image, and we can confirm the existence of several galaxies. 45 cm Newtonian 2 minutes x 30 sheets (total exposure 1 hour) 2 x 2 binning ASI071Mc Pro 2022-03-03
Venus 2022-03-01 (UT) Venus at dawn after the inner conjunction. The expected seeing condition is very poor. Although it is an image of bad seeing, the south edge is bright in UV, the dark color feature of unevenness near the terminator, and the dark feature of rounded shape in the center of the IR-1000 image?
It is a quick image of the summer star cluster during the light hit before the image of Venus in the early morning. Each 1 minute x 5 images, low altitude and poor image. Summer celestial bodies are just around the corner in early spring! 45cm Newtonian 2022-03-02
Dwarf Galaxy Leo II (Leo II) -2 There were images captured by the Subaru Telescope (8m) on the Big Island of Hawaii, so I arranged them. The field of view is about the same, but it’s a great resolution.
