The Orion Hill (オリオンの丘)IC434,NGC2023,NGC2024,IC432

Originally, it was an area that I thought was the subject of First Shot with different equipment, but unfortunately it was discovered that this equipment could not be taken.
If it doesn't work, it won't work. But I really wanted to take this picture, so I took it with existing equipment.
Just last week, my astrophotography friend Mr. Iwasaki shot this area and got great results, so I talked a lot about it.
He said that it would be nice to have a V channel, so I shot Ha, Oiii, Green. Pallete is based on Ha-HaVOiii.
I wanted to get the red color of H-Alpha as it is, but when I tried to visualize the hill part, it turned pink instead of red.
I wanted a stronger image, so I settled on this color as a result of trial and error mixing various Palettes.
The FOV remains the mirror shift of the primary focus of the C11 primary mirror.
Thank you Clear Skies !!
