NGC4565 2022-02-06

NGC4565 2022-02-06 NGC 4565 (Caldwell 38) is a spiral galaxy in the constellation Coma Berenices, with a distance of about 30 to 50 million light-years, a galaxy seen from the side. m = 10.4 diameter / 15.9’× 1.85′ It was a feature seems to be poor.

Asteroid Kawakami (8413) 2022-02-05

Asteroid Kawakami (8413) 2022-02-05 At dawn, I was finally able to capture the asteroid Kawakami (8413) at the southern end of Libra. I thought it would be easy to catch an asteroid of about 18 mag with a 45 cm aperture, but it is a difficult magnitude under low altitude and poor seeing conditions! Thanks for the repair of the equatorial mount, it was finally fulfilled by the third challenge.

NGC3628 2022-02-03

NGC3628  2022-02-03 Unbarred spiral galaxy, 10.2 mag, located about 35 million light-years away in the direction of Leo. Seeing is good, and small galaxies are scattered around the nebula. A line of asteroids (37996, 17.3m.) can be seen in the lower right of the nebula.

James Webb Space Telescope

JWST (James Webb Space Telescope) 2022-01-31 New Space Telescope: JWST has arrived at the planned position (L2), so I tried to get it. From the position estimation table of Hidenori Nohara in Utsunomiya City, it is reflected in the stripes between the stars in the background in the Milky Way in winter. Thank you very much for data.

HH222 (slightly south of the M42 Nebula in Orion)

2022-01-28 HH222 (slightly south of the M42 Nebula in Orion) Imaging of the Herbig-Haro object, which was the subject of research by astronomers, was the subject of research with the telescope of the observatory, but with the development of imaging technology, it has become possible with amateur telescopes and is taking on the challenge. Especially in the vicinity of NGC 1999, many HH objects have been discovered and it is possible except for small ones. HH-222, commonly known as the Waterfall Nebula. It is about 1,500 light-years from Earth. Normally, infrared light will give a better image, but since it is a slightly dark object, the total exposure will be longer.

NGC1999 and HH1, HH2 (Herbig-Haro Object)

NGC1999 and HH1, HH2 (Herbig-Haro Object) 2022-01-24 It shines with the light of a new mass star called, and the distance from the solar system is 1500 light. It seems to be a hollow that is not in the black shadow on the right side. HH1 and HH2 on the lower side are small and dark, and it is a celestial body that is difficult to photograph even with 45 cm telescope.

Horsehead Nebula  2022-01-07,08

Horsehead Nebula  2022-01-07,08  Total exposure / 3.5 hours After the repair of the equatorial mount was completed, the strength and tracking accuracy were improved, and the image of the tracking test was taken. 45 cm reflection ASI071MC PRO. Thank you for the reborn performance.

I want to capture the Orion Nebula in three dimensions!

I want to capture the Orion Nebula in three dimensions! M42 has a bright area around Trapezium, and the internal pattern is complicated and looks very mysterious. The surroundings are also complicated. I thought it was a fake three-dimensional image of the wings of a butterfly, so I tried it. I just took pictures with different exposures and combined them, but when I looked at the image, I got an image that felt like the center was in the back and the surroundings were in the foreground. 2022-01-04 45cm Reflective ASI071MC PRO

Try with a 45cm telescope

Try with a 45cm telescope. Recent back-illuminated CMOS color cameras (Neptune-C II) have high sensitivity in the infrared region, and the RGB color balance is lost. However, the sensitivity is high. When examined with 45 cm + 15 seconds exposure (gain 400, 360 sheets), a star with m = 20.91 was confirmed. Is it a benefit of high infrared sensitivity? If its good seeing and transparency, optical axis of the telescope, and tracking are improved, it will be possible to capture the target 21 etc.
