Description

First Orion of the year!

I had to stay up almost until the sunrise to capture my sub frames, since it's so early in the season and to be able to see Orion from my backyard, I have to wait until 3 am. But it was totally worth it.

The final image is a result of 147 light frames stacked with Deep Sky Stacker and processed in Adobe Photoshop CS6. Each light frame is shot at ISO 800 and 30 sec exposure, with my new Nikon D3300 full spectrum modified, from my backyard, Bortle Class 7 sky.The DSLR was attached to my Sky Watcher Black Diamond 150/750 reflector scope on Sky Watcher EQ3-2 mount, using only motor drives for tracking. 

It's my first shot using my new modified DSLR and although I have to get better at processing full spectrum data, I am pretty happy with the result. I would really like to read your comments so I can improve and get better images.

Thanks for checking!

Orion Nebula, also known as Messier 42, 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. It is 1,344 ± 20 light-years away and is the closest region of massive star formation to Earth. It is estimated to be 24 light-years across. 

The entirety of the Orion Nebula extends across a 1° region of the sky, and includes neutral clouds of gas and dust, associations of stars, ionized volumes of gas, and reflection nebulae. 

The current astronomical model for the nebula consists of an ionized (H II) region, roughly centered on Theta Orionis C, which lies on the side of an elongated molecular cloud in a cavity formed by the massive young stars. The H II region has a temperature ranging up to 10,000 K, but this temperature falls dramatically near the edge of the nebula. The H II region is surrounded by an irregular, concave bay of more neutral, high-density cloud, with clumps of neutral gas lying outside the bay area.

The Orion Nebula is an example of a stellar nursery where new stars are being born. Observations of the nebula have revealed approximately 700 stars in various stages of formation within the nebula.

Many Deep Space Objects lie near Messier 42. Those captured in this image are: Mairan's Nebula - Messier 43, Running Man Nebula (which consists of NGC-1973, NGC-1975 and NGC-1977) and NGC-1980. NGC-1980 is a young open star cluster associated with an emission nebula.
