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.
Full moon 2022-02-16 In the afternoon, I changed the position of the 45 cm Newton oblique mirror and aligned the optical axis. Recalling the old story, I challenged “the full moon where the crater can be seen”. There was a little thin cloud, so I processed it in monochrome mode, and now I can see the crater of the full moon without shadows!
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.
Sirius’s companion star 2022-02-12 Sirius B because seeing was a little better. It seems that the optical axis was slightly off. I know the video image well. It could not be confirmed visually.
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
I tried mosaic software that makes the entire feature of the moon. I hadn’t used it until now, but Photoshop’s Photomerge can easily synthesize mosaics, and it can be very useful on the moon! Why is it used? I regret it, but I will do my best from now!
NGC2903 2022-01-28 NGC 2903 is a barred spiral galaxy about 30 million light-years away in the direction of Leo. Brightness 8.8 mag The spread of the upper and lower arms is wonderful, and the north side is divided into two. 45 cm Newtonian / seeing was bad and stars image was poor.
Moon 2022-02-07 I took a image of the moon after a long time. The altitude of the moon is high this season. Seeing condition is poor and 45 cm is squeezed to 16 cm for use!
