The Orion Nebula (also known as Messier 42, M42, or NGC 1976) 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 with apparent magnitude 4.0. It is 1,344 ± 20 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 (so its apparent size from Earth is approximately 1 degree). It has a mass of about 2,000 times that of the Sun.
The Orion 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.

One of my first astrophotos with the CPC925 reflector and my Nikon D800 camera was of the Orion nebula. I used the program Nebulosity to stack some 5 exposures taken in my Stuvsta garden, December 2014.

So where is the Orion nebula? Well, it can only be seen in the winter when the Orion constellation is visible. You find the nebula as part of the belt of Orion.

Using a telephoto lens of 70mm on the Nikon D800 camera, the M42 nebula becomes more visible. Photo in Åva March 2016. Astrotracker used.

Switching to 300mm focal length brings out more detail of the nebula. On top of the reddish M42 nebula another, reflection type nebula called “The running man” becomes visible. The trail of a meteor is also visible.
26*15s exposure at ISO800 with Nikon D800 camera in Stuvsta, January 2016. Lens is 200mm but using DX-format. Astrotracker used.

Another promnent nebula complex lies a bit above the Orion nebula, close to the belt of Orion. Here we can find the flame nebula and the horsehead nebula.

Using my APO107 refractor with the Nikon D800 camera gives more detail than the telephoto lenses.
