"THE GREAT ORION NEBULA"
- Deepsky 750mm LSHO Stars: RGB
- Constellation Orionis
Another refreshing elaboration of the great Orion Nebula - and it's far from over ^^
Let the creativity run free, regarding the coloring, I call it "Fresh Banana Look", it somehow reminds me of an ice cream dessert in summer *g*
Narrowband filters for hAlpha, SII and OIII were used, the star colors come from RGB recordings. The colors were selectively adjusted by me, so we're pretty much in the "pretty pictures" range here
But it's also fun every now and then
The Orion Nebula (M42 or NGC 1976) is an emission nebula in the constellation of Orion. Due to the high apparent brightness of its center above the 4th magnitude, the nebula is clearly visible to the naked eye as part of Orion's Sword south of the three stars of Orion's Belt. Overall, it has an angular extension of about one degree.
The Orion Nebula is a subregion of the interstellar molecular cloud OMC-1 in the Orion molecular cloud complex. It consists mainly of hydrogen. Stars form in the nebula, whose ionizing radiation makes the nebula shine in the visible range. It is therefore also classified as an H-II area. At a distance of about 1350 light-years, it is one of the most active star-forming regions in the galactic neighborhood, which is why it is a preferred study object for studying star formation. It is expected to evolve into a Pleiades-like open star cluster.
The main ionization source of the Orion Nebula is the star θ¹ Orionis C1, which is also one of the most luminous stars known with more than 200,000 times the luminosity of the Sun. However, the immediately adjacent and similarly configured De Mairan's Nebula has a different ionizing source and is therefore not part of the Orion Nebula.
