2-22 M42 Crop of Comb-1xHa-3xOIII 207Min STCrHDRJ
We captured the Great Orion nebula (M42 or NGC 1976) on February 22, 2021. This is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. We also captured the nearby companion nebulae M43 and Running Man nebula (NGC 1977) in the same frame.
The Great Orion nebula is ~1,350 light-years away and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2,000 times that of the Sun. This nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features.
The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks and brown dwarfs within the nebula, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.
We captured our image using a Stellarvue Access 80mm refractor fitted with a Stellarvue Field flattener and a dual NB (Narrow Band) filter for capturing deep red H-Alpha and blue/green OIII emissions. The imaging camera was an H-Alpha modded Nikon D5300 at ISO 1600. Exposure details were - f7 and a total exposure time of 207 min (103x 2.01 min). We separated the mono HA and mono OIII files in APP (Astro Pixel Processor), reduced gradients in each mono file and then recombined them in APP and post-processed in StarTools to get this image. Enjoy!
