2021-01-10 NGC 3628 (Leo, a non-barred spiral galaxy located about 35 million light-years away) The central band structure is overwhelming, and many small galaxies are scattered around 45 cm Newtonian ASI071MC Pro LPR-N 1m x 30 frame
NGC2392 (Eskimo Nebula) NGC3242 (NGC 3242) NGC2438 (Puppis) Both are small and dark objects with a size of 40 “to 1′, such as M = 10, but with a 45 cm telescope, I can watch the colors and enjoy watching at them. Since they are small objects, its increased them to 200%.
LP 540-5 High proper-motion Star Can you see the fast-moving stars of proper motion that I took the other day? I tried it with two of my star friends. I used a 5mm eyepiece and looked at it at 367x with 45cm newtonian telescope, but we couldn’t confirm the target star of the faint star because of the bad seeing, so it was carried over to the next time. Can you see it visually? Please. This is the material image of this time.
Hubble’s Variable Nebula-2 A friend of mine who saw the NGC2261 image pointed out that there is a large star with proper motion compared to the image taken with Paloma-5m telescope (1948). If you look at the Paloma image, Subaru Telescope (1999), and 2021, you can see the movement of stars for 73 years!
2021-01-09 23:47 (JST) 45cm F/4 ASI071MC Pro Is the very faint object (inside the black-and-white inverted circle) just south of Hubble’s variable nebula a diffused nebula? Hubble’s Variable Nebula [2], Caldwell 46 Constellation Monoceros Magnitude (V) 9.0 Apparent diameter 2′ Classification Variable nebula (reflection nebula [1]) position Epoch: J2000.0 [1] Right ascension (RA, α) 06h 39m 10s [1] Declination (Dec, δ) + 08 ° 45’00 “[1] Distance 2,500 light-years From Wekipedia
NGC4565 Galaxy (Needle Galaxy) Luminous intensity 9.6 mag, apparent diameter 16.2′ 2021-01-10 45cm F / 4 Newtonian reflector coma collector LPR-N filter ASI071PC Pro -20 ℃ 30s x 30 frames. It seems that the dark body inside is warped at both ends of the nebula.
M42 (Orion Nebula) 45cm Newtonian reflector F / 4 coma collector 60s x 10 sheets UV / IR cut filter ASI071MC Pro Gain 0 -10 degrees This is a test image of a cooling color camera that arrived at the end of last year. The cooling camera is the first in 15 years, but the latest one has no fan vibration. Although it has an ASP-sized angle of view, the current 45 cm reflector is good because Low light loss at the edge of the field of viewi. ASI color cameras have high green sensitivity but are within the adjustment range.
Rosette Nebula’s Harbic Harlow object “Rosette HH1” The other day, I was able to take a picture again from Mr. Mizutani’s information and clearly confirm its existence. In the literature, the Harbic Harlow object is an atomic star. It seems that the jet extending into outer space is hidden behind molecular clouds and cannot be seen with visible light. Although it looks faint even in a color image, it is clear in monochrome of ASI290MM (30 seconds x 30 frames, struggling to stack).
