Messier 42 is the most popular nebula to photograph! And it is easy to capture!
M42 looks amazing in photographs through both telescopes (as seen below) and DSLR lenses (scroll down!).
The following photo was taken through our 8” telescope with a total exposure time of only 1 hour!
M43 (The little ball shaped nebula on the left of the heart shape of M42) is visible, as well as the Running Man nebula (top left). When capturing it, be sure to also take a few short exposure shots for the bright core as well as the Trapezium cluster!

NEBULA OR NEBULAE?
The Orion nebula is almost always photographed with two other nebulae: M43 (De Mairan's nebula) & NGC Sh2-279 (The Running Man nebula). See a close up of both below.
Messier 43 is an H II region that is pretty much part of M42. Both are only separated by a lane of dust.
Sh2-279, or Sharpless 279, or... let's make it easier, the Running Man nebula, is located just to the left of M42/M43.
Make sure to frame your camera properly and get all of the Running Man, you do not want a cut nebula in your magnificent image.
LOCATING THE ORION NEBULA
M42 is the easiest nebula to find. It is located in Orion’s sword and is obvious to spot as it looks like a star. It lies between other deep sky objects, such as the Horsehead and Flame nebulae, M78, and even the Witch Head nebula.
Messier 42 is one of the brightest nebulae in the sky, and is easily visible with the unaided eye even though it looks just like a regular star. The nebula is an amazing sight through binoculars, as you can make out its shape as well as its bright core.
Any size telescope will reveal more of the gases with different shades of gray. You will also be able to spot the four stars that form the famous Trapezium cluster in the core of the nebula.
Cool Facts
Discovered in 1610
The nearest stellar nursery to Earth
The Trapezium is an open cluster that powers the gases all around
Wide-field Astrophotography of the Orion Nebula
M42 can easily be photographed without a telescope! We recommend that you aim for the emission nebula Barnard's Loop. You can also get IC 434 and M78 in the same frame if using a 85m or 50mm lens!
Below is Barnard's Loop, we spent 7.2 hours on the imaging (watch Episode 8!), using a 50mm lens, also tracking the stars with our Atlas EQ-G motorized Mount.

GEAR USED:
Camera: Canon 7D Mark II
Lens: Canon EF 50mm f/1.8 STM Lens
Mount: Atlas EQ-G motorized Mount
Processing: Pixinsight
ACQUISITION DETAILS:
Total Exposure Time: 7.2 hours
RGB Exposure Time: 3.6 hours
Hydrogen Alpha Exposure Time: 3.6 hours
Exposure Time per frame: 6 minutes
73 lights, calibrated with Darks and Bias

SINGLE SHOT & PROCESSING OF M42
Processing the Orion Nebula is very easy! The only trick is to know where the nebulosity is supposed to be, and to not mess up the background extraction at the beginning!
If you have the chance, take the time to travel to a dark zone to photograph this target (and every other target as well...)
Below you can see the huge difference between a 30-second single shot from our parking lot in Las Vegas, and a single shot from our imaging spot near the desert. If we can, we will try to update this post in the future to show what a single shot from a Bortle 1 zone looks like!
CAMERA LENS ASTROPHOTOGRAPHY OF M42
As we said above, the Orion Nebula can easily be captured without a telescope. It is a great idea to capture the entire Orion complex with a small lens, but it is also a good target for telephoto lenses, both tracked, and untracked. See our images of M42 using a 300mm lens with and without a tracker below! Both photos have a total exposure time of 3.5 hours.
We got this image using our t3i with a 300mm lens f/5.6 on a simple tripod! Because of the focal length of the lens, we could only do 6 second exposures before getting star trails.
This image is, obviously, the same nebula, but this time using an iOptron SkyTracker !
Because of the tracking, we were able to do 3 minute exposures instead of 6 seconds!
Notice how the Running Man nebula is much more visible, and how M42's shape is more like a heart than in the untracked photo.
THE ORION NEBULA WITH STELLINA
We imaged the Orion Nebula with the Stellina observation station from Death Valley, California. We only spent a total of 10 minutes on it but the result is impressive!
It took just a few minutes between the moment we took Stellina out of our trunk and the moment we started imaging with it. You can see our Unboxing video of this product in the REVIEW tab of this website [coming soon], as well as a full review of this futuristic astrophotography instrument.
The Orion Nebula from our backyard
February 2020
The Orion Nebula was our second attempt at doing Astrophotography from our very light polluted backyard in Las Vegas. If you'd like to see what our very first image from home looked like, make sure to visit our California Nebula post!
Using the TRIAD Quad-band filter on our ZWO ASI 071MC camera, we spent just 20 minutes on Messier 42 to see what the results would look like... We were stunned. We did 30 second exposures to ensure that the core would not be blown away, and as you can see, the Trapezium cluster is clearly visible!
GEAR USED:
Camera: ZWO ASI 071MC
Telescope: Orion 8" Astrograph f/3.9
Mount: Atlas EQ-G motorized Mount
Coma: Baader MPCC Coma Corrector MkIII
Guiding: ZWO ASI 290MM Mini
Acquisition: ZWO ASIAIR
Power: Pegasus Astro Pocket Powerbox
Filter: TRIAD Ultra Quad-Band
Processing: PixInsight
ACQUISITION DETAILS:
Total Exposure Time: 20 minutes
Exposure Time per frame: 30 seconds
Gain: 90

FINAL THOUGHTS
Messier 42 is by far the best nebula to not only photograph but observe in the night sky. We'd love to see your own versions of the Orion Nebula! Post them below if you have photographed this target before :)
If you would like to get our photo of the Orion Nebula as a print, or other, you can support us and see some options HERE.
