Reflection Nebula and Small Open Cluster In Monoceros (vdB 80)

Reflection nebula and small star cluster in Monoceros
Like the Pleiades, this is an open cluster of young stars and the molecular cloud that gave rise to it.
Red hydrogen molecular clouds spread out in the background.
The combination of nebula and star cluster is truly captivating.
It's located south of the center of the Winter Triangle, making it a lively area with the stars of the Milky Way mixed in.
I forced myself to correct the underexposure by raising the bottom level, which resulted in a lot of noise, but I got a sense of the atmosphere, so I'll probably collect more signals next season.

いっかく獣座にある反射星雲と小さな星団
プレアデス星団と同様に若い星達の散開星団とその元となった分子雲。
背景には水素の赤い分子雲が広がっている。
星雲と星団のコンビネーションは本当に惹かれるものがある。
位置は冬の大三角形の中心の南に位置するので天の川の星達もまざり賑やかな場所だ。
露出不足をボトムのレベルの底上げで無理やり調整したのでノイズが出まくってしまったが、雰囲気はわかったので、来シーズンに追加シグナル収集かな。
