The Upper Orion Sword Cluster(オリオンの剣散開星団) NGC1981

A few days ago I rushed into my friend Nelis's house in the middle of the night and watched his Orion Nebula shoot.
After taking a few shots, clouds appeared and the shooting was canceled, but the last 1 Frame shot was still on the monitor. The nebula was thin because of the clouds, but on the contrary, this cluster was conspicuous and left a tremendous impression on me, so I wanted to take a picture.
Orion's sword made up of Orion's small three stars, as opposed to Orion's belt made up of Orion's three stars.
Here you will find the Orion Nebula and the Running Man Nebula, which everyone wants to capture once a year.
This cluster is just north of the Running Man Nebula.
Like the other Objects around the Orion Nebula, it is probably one of the Poor Objets whose existence is unknown, either taken alone or mentioned.
The contrast between the strong blue light stars that make up the cluster and the red stars that surround it is beautiful.
Next time, I think it's better to shoot 1 Frame with a long exposure and a wide FOV.
