M27 was the first planetary object discovered by Charles Messier in 1764. We imaged this target several times with different equipment, Bortle locations and skill level. We will show you all our attempts below!
Object Designation: M27
Also known as: The Dumbbell Nebula
Object Type: Planetary Nebula
Distance: 1,360 light-years away
Discovered in: 1764
Messier 27 is bright and at first, appears a little small, but large expansions of gas can be seen around the nebula in long exposure photos. It can easily be spotted with a telescope or even binoculars from a dark location. The best time to photograph M27 is in Summer but the object will stay high in the sky in Fall as well.
Imaging the Dumbbell Nebula from home with a monochrome camera
June 20, 2020
At the end of June 2020, I decided to spend several nights on Messier 27 from the backyard. I'm not sure why but I got over-confident and assumed it would be completely fine to image it in narrowband even during a full moon. This was a mistake... especially since our backyard is already extremely light-polluted at Bortle 9!
The 5 nights we spent on this target were all when the moon was very bright and up, and now I wish I waited a couple of weeks before starting this project. It would have probably been fine to just shoot Hydrogen Alpha, and maybe Sulfur as well, but it was most likely a terrible idea to shoot in Oiii as well during the full moon as this is the narrowband filter that blocks the least amount of light pollution.
I made a video about the whole process which you can watch HERE!
I also believe that with this camera and from the bright backyard, 5 minutes of exposure is too much for this object as the core was way too overblown when stacked and it was a real pain to reveal any detail while processing it!
Camera: ZWO ASI 1600MM
Telescope: 8" Astrograph
Total Exposure Time: 22.5 hours
Exposure Time per frame: 5 minutes
Imaging the Dumbbell Nebula with a stock DSLR camera
October 3rd, 2017
This target does not require many hours to get great results. We only spent 1 hour and a half worth of 6 minute exposures to get the result below, and you can easily distinguish the shape of a dumbbell. You can also see a bit of the red "X" striking in the center of the nebula, which is not easy to get without spending a few hours on it. We imaged this from a Bortle 4 zone, which of course helped!
Camera: Canon 7D Mk II
Telescope: Orion 8" Astrograph f/3.9
Mount: Atlas EQ-G motorized Mount
Total Exposure Time: 1.6 hours
Exposure Time per frame: 6 minutes
16 lights - 30 Darks - 30 Bias
Locating the Dumbbell Nebula
Messier 27 is the second brightest planetary nebula, and large enough to be visible with binoculars and small telescopes. Due to its high surface brightness, a telescope will yield more details in the gases of the nebula, and you may even recognize the shape of a dumbbell!
The Dumbbell nebula can be found inside the famous Summer Triangle (composed of the bright stars Altair, Deneb, and Vega), in the constellation of Vulpecula. Star hop from Altair and head down towards Deneb in a straight line. You will land on M27 about one-third of the way there.
Also note that an open cluster, NGC 6830 containing just about 30 stars lies just a couple degrees west of the nebula.

Single Shot & Processing of M27
Below you can see our single shot of M27 using our stock DSLR camera. It is surprising how colorful and crisp it already looks! It is also hard to believe that 16 of these frames don't make that much of a difference when stacked and processed (2020 update: Well, maybe we just sucked at processing back then).
The biggest challenge in the processing is to bring out the red "X" striking in the center of the nebula.
This is not easy task with a stock DSLR unless you spend a lot of time on it, but it is achievable.
The key is to image from a zone that is dark enough, and make sure to bring out the red gases during processing. As always with red gases, a Hydrogen Alpha filter will help!
Messier 27 with a Smart Telescope
In 2019, we reviewed the smart telescope "Stellina" and took an image of M27 from both the very light polluted Las Vegas Strip, and the very dark Death Valley.
The image on the left is the one we took from the Strip (Bortle 9!) and we must say we are impressed considering this was only 12 minutes of total integration time!
Make sure to read our full review of Stellina if you'd like to see the comparison shot between the Las Vegas Strip and Death Valley, as well as many other images taken with this device.
Video: Photographing M27 from the backyard during the full moon
Want to know how I captured our 2020 version of the Dumbbell Nebula? Watch the video below as I image M27 with narrowband filters from the backyard!
The Dumbbell Nebula is a one of the easiest nebulae to photograph in the night sky. As you can see above, a single shot is already very impressive with an unmodified DSLR camera! We are a bit disappointed in our 2020 attempt mostly because we expected more for 22 hours of exposures, but we believe it is our own fault for shooting it during the full moon! We shall get a better image in a third attempt at some point!
