Perseus galaxy 2021-11-27 45cm reflection 1mx30 frame ASI0871MC Pro Monochrome color image. Abell426 A large group of more than 1000 galaxies called the Perseus cluster of galaxies
C / 2021 A1 Leonard 2121-11-28 04:24 (JST) 45cm F / 4 Newtonian Field / 40′ x 25 ′ 30s x 10 frames The image is worse than yesterday, probably because of the nearby crescent moon, moonlight, and bad air. You can see a little fine structure of the comet’s tail
C / 2021 A1 Leonard 2121-11-27 04:30 (JST) 45cm F / 4 Newton newtonian Field / 0.5 ° 30s x 20 frames The tail of the comet has become clear.
C / 2021 A1 Leonard 2121-11-26 45cm F/4 newtonian 30s x 20 frames There was moonlight, but the transparency was good, the comet head was green, and I am looking forward to the future.
Orion Nebula 2021-11-17 Atmosphere of M42 color peeking at 45cm! The image is rotated 180 ° and viewed.
Andromeda’s Parachute (Quasar) 2021-11-07 A celestial body 11 billion light-years away. The three shapes A, B, and C are umbrellas, and D is the base arrangement. The resolution depends on seeing condition, but the separation of the three stars is very strict. 45㎝ F/4.5 Newtonian
M42 2021-10-05 You can see the high sensitivity in the infrared region by looking at the M42 color image (UV / IR cut filter) and infrared image (IR-850) with Neptune-C II. Color image (Shutter = 764.3msGain = 397 Frames captured = 351) Shutter = 957.1ms Gain = 459 Frames captured = 203)
