Coma Cluster
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
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!

M63（NGC 5055）
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.

M64( NGC 4826)
M64 (NGC 4826) is a spiral galaxy in the constellation Coma Berenices. M64 (NGC4826) Galaxy (Black Eye Galaxy) Coma Berenices, luminous intensity 8.5, apparent diameter 9.3′, distance 19 million light-years The rotation of the central vortex and the rotation of the outer vortex are opposite. It is believed to be a remnant of the collision and coalescence of two galaxies in the past. 2021-02-21 45cm newtonian

M57 (Lyra, Ring Nebula. Luminous intensity 9.0 mag, apparent diameter 2.5′).
M57 (Lyra, Ring Nebula. Luminous intensity 9.0 mag, apparent diameter 2.5′). A white dwarf (15th magnitude) in the center of the nebula. Next time, I would like to see it with a 45cm reflection. C1296 (14th magnitude star) on the upper right is a dark and pale galaxy.
