NGC3190 An exoplanet at the head of Leo. The center right is NGC3187 (S-shaped rod-shaped spiral galaxy) V grade / 13.4 45cm newtonian. 2022-02-23 The optical axis and guide were good, but seeing condition was poor and the details of the nebula were not shown.
NGC 2857 is a spiral galaxy of Ursa Major, V magnitude / 12.27 You can see many galaxies around. 45cm F / 4 newtonian 2022-02-22
NGC1977 (Running Man Nebula) The contrast between the red inside the nebula and the blue gas around it is beautiful. After the rain, there was no dust in the air, and the transparency was good.
M43 (video) 2022-02-18 On the north side of M42, the equivalent of the feather head, which is different from the bright place of Trapezium, is also a complicated nebula. Visually, if the conditions are good, it should look like a video image!
NGC2392 (Eskimo Nebula) 2022-02-17 I edited the video of the visual image at 4x speed. The influence of the moonlight is small, and a little faint feature inside the circumference of the nebula can be seen.
IR (685nm) image of M42 2022-02-14 In IR, there are many stars hidden inside the gas in the center of Orion M42. Even in a color image, you can see bright things, but you cannot see dark things. The IR image is made into false color to make it easier to see.
Video of the central part of M42 (Orion) We have reproduced the central part of the M42 as seen through a 45 cm telescope. The way I feel the color is different depending on the individual, but I feel green and purple.
NGC2818 2022-02-12 A planetary nebula at a low altitude (declination-37 °) in Pyxis. It was a bright condition in the southern sky of the moonlight, but the transparency was good and I could barely catch it. A small, dark planetary nebula, no details visible. ｍ＝ 12.5. 45 cm F / 4 Newtonian Neptune-C II UV / IR cut 2 x 2 binning 5s x 300 frame
Cone Nebula (part of NGC2264) 2022-02-05 Diffused nebula in Monoceros. Since it is a pale celestial body, it is only in the center at 45 cm. Obviously not enough exposure!
