45cm telescope scenery. Last night, the polar alignment of the equatorial mount was performed for the first time in 5 years in order to improve the period deck motion of star tracking and improve the accuracy of automatic introduction. Equatorial mounts that are not aligned with the polar axis are out of the basics! The telescope landscape has been HDR processed to deceive the surroundings.
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.
Mars 2021-01-09 (UT) The apparent diameter is 9.6 arcsec, which is smaller and does not capture the SPC or details. Clouds that look like polar clouds can be seen around the north side.
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.
