AT2021dhg in M64 “Black Eye Galaxy”. Thank you for the information, Mr. Toshihide Noguchi. The discovered supernova on 2/15 was also shown in my image 2/21. The brightness at the time of discovery was about 20 mag, but it seems that it became brighter on the 21st.
NGC3344 Galaxy (Leo Minor) Luminous intensity 10.0 equivalence Diameter 6.9′ RA 10h43m31.1s Declination +24 ° 55’12 “(J2000) You can clearly see the faint spiral structure to the outside. The surrounding area is dotted with many small galaxies. 45cm newtonian
M13 (NGC6205) Globular cluster Luminous intensity 5.9 mag, apparent diameter 16.6′ 2021-03-15 From the center to the outside of the globular cluster, you can see the black lines with few star arrangements. 45 cm Newtonian
Planetshine 2021-03-15 I enjoyed the scenery of the setting planetshine. 300 mm, 105 mm lens, Mayumi, Hitachiota City
2021-03-15 Hydra Cluster (Abell 1060) is a cluster of galaxies containing 157 bright galaxies, which can be seen from the earth in the direction of Hydra Cluster. 45㎝ Newtonian
The Coma Cluster (also known as Abell 1656) is a large cluster of galaxies containing more than 1000 galaxies that have only been identified. The average distance of the cluster of galaxies from Earth is 99M Parsec (321 million light-years). 2021-03-15 45 cm Newtonian
Twin Quasar 2021-03-08 A quasar that exists in the universe about 9.1 billion years ago, located about 13.85 billion light-years away from the earth in the direction of Ursa Major. It is an example of the gravitational lens effect discovered for the first time. I took a image of the celestial body introduced by Mr. Konnai from Fukushima Prefecture, but at a brightness of 16.7 mag, even a 45 cm telescope would not be visible!
Abell2151 (Hercules Cluster) 2021-03-10 A cluster of galaxies with less than 100 galaxies located near the boundary with the head of the snake, with a brightness of 14 magnitude or less and a distance of about 460 million light-years. A mixture of small galaxies with different arm shapes.
M63 (NGC 5055) 2021-03-08 Canes Venatici, distance / approx. 24 million light-years Large spiral galaxy with beautiful spirals. 8.6 mag, visual diameter 12.3′ The fine and complicated spiral structure and the large dark feature on the outside are wonderful. If you look closely, you can see that the pale nebula on the right side, which is a little far away, and the large dark spiral are connected. In addition, there are two spindle-shaped galaxies at the right end of the nebula (see the monochrome inverted image on the upper left) 45 cm newtonian.
