The M46 Region In Winter Milky Way With NGC2438,2425

On a holy Christmas night, I wanted to see the stars filled up, so I pointed my telescope at the M46 in the Milky Way in winter.
Wow, the stars are beautiful after all.
Since it is a 70mm telescope, Usually shoot the adjacent M47 with the same angle of view, but the contrast between the two bright white stars to the left of the M46 and the bright red star below was wonderful, so I decided to ignore the M47. ..
The central star group is the M46 diffused nebula, and the green star in the upper left is the planetary nebula NGC2438. The only colorful and impressive monotone cluster. NGC2425 is a small orange cluster in the direction of 3 o'clock on M46. Both size and color are symmetrical with M46.
In fact, there is a nebula called "Calabash Nebula" just to the upper left of the NGC2438 planetary nebula. It seems that this is a nebula that is about to become a planetary nebula, but unfortunately I couldn't capture it that much. I want to shoot it in target someday. Since no major catalog name is given, the technical name OH231.8 + 4.2. Seem to be the only ID.

実はNGC2438惑星状星雲のすぐ左上にもCalabash Nebulaと呼ばれ星雲がある。これは惑星状星雲になりかけとの星雲だそうだが、残念ながらそこまで写しきれなかった。いつかそれをTargetに撮影してみたい。メジャーなカタログ名が付与されていないため、技術名としてOH231.8+4.2.いう識別番号が唯一のIDのようだ。
