LDN 1622 - The Boogeyman Nebula in Orion

Updated: May 18, 2023

LDN 1622 is a dark nebula in Orion. It is known as the Boogie Man Nebula due to both its shape and its dark color.

LDN 1622, just like all dark nebulae, is not an easy target, and many hours of exposure are required to get a beautiful result.

Object Designation: LDN 1622

Also known as: The Boogeyman Nebula

Constellation: Orion

Object Type: Dark Nebula

Distance: 500 light-years away

Magnitude: Unknown

Discovered in: Unknown

The Boogieman Nebula zoomed in

The Boogeyman Nebula has a diameter of just about 10 light-years, making it pretty small if we compare it to most other nebula in the Orion region. LDN1622 is much closer to Earth than M42, M78 and the others though, which is why it appears large.

As you can see on our cropped image on the left, the nebula is made up of dark dust, including completely black opaque gas in some areas. These gases are so thick that they fully hide light from stars behind them. The nebula is also located in front of some faint red hydrogen alpha gas, slightly visible here as well.

The image below is the result of just 4.5 hours of total exposure. The target was only high enough in the sky until about midnight, so it was not possible to spend more time on it. It was taken from a Bortle 3 zone in Nevada, one hour away from Las Vegas.

How to find LDN 1622?

How to find the Boogieman Nebula LDN1622 in Orion, constellation map

The Boogieman Nebula can be found in the most recognizable constellation in the Winter sky: Orion.

Don't expect to be able to spot it with your naked eye, a pair of binoculars, or a telescope. This target is way too faint and, obviously, too dark to be seen visually. Filters won't help either.

If you are trying to point a DSLR camera/lens to this target, know that it is not too difficult to find.

The Boogeyman Nebula is located kind of in between two bright stars, Betelgeuse and Alnitak. First, take a quick test shot of the Orion region and spot Messier 78 on your camera screen. This should be easy if you take a long exposure with a 50mm lens wide open. From M78, try to tell how Barnard's Loop is angled. The loop should will pass just "below" M78. The easiest way to find LDN1622 is to simply jump over the loop from M78. The dark nebula lies at about the same distance on the other side of the loop.

if you are using a 50mm or even 85mm lens, you will have the Boogeyman Nebula in your frame for sure as long as M78 is not too close to the edge!


Processing the Boogeyman Nebula

LDN 1622 was pretty difficult to process. Just like every dark nebulae out there, it is tricky to bring out detail or brightness in the dark gases without adding noise to the overall image, even when playing with masks.

It is also difficult to do a correct background extraction as you can't really tell where there is and isn't gas over the image. Using a reference image from other astrophotographers can sometimes help when using the Dynamic Background Extraction on PixInsight as you'll be able to better know where to place your points.

Below you can see a single shot so that you can know what to expect. It is a 10-minute shot, so pretty long but you can see the nebula starting to appear near the center. The Hydrogen-Alpha gas from Barnard's Loop is easily visible on the top right, and this is without filters!

Final Thoughts

The Boogeyman Nebula is a great dark nebula that is very close to many more popular deep-sky objects in Orion. It is a great target to attempt if you are looking for a challenge or would like to capture your first dark nebula.

I'm calling a hoax. Anyone who knows anything about astrophotography knows that what really happened is that you had a random astronomy picture on the table, Gilbert knocked over a coffee cup, and Dalia covered for him by saying, "OOOhhh... Look! You captured the The Boogeyman Nebula!"

Kidding aside, it's an awesome picture. When I have time, I'm going to have to so some research about LDN 1622. Since you say it can't be seen with a telescope, I'm curious as to how it was discovered.

Correct. It was discovered by William Herschel in 1787. His major tech-advances were large enough telescopes to discover that some nebulae were actually open clusters, and he's credited as being the pioneer of astronomical spectrophotometry. What made him famous at the time was his discovery of Uranus: however, I think his pioneering of astronomical spectrophotometry and his discovery of infrared radiation did more for the science-side of astronomy than his discovery of a new planet. He was one cool cat!

Nice job! That’s about 23k worth of equipment though.

The Mach-1 is from our friend Patrick who is planning on selling it in about 3-4 months (if you are interested you can email me and I'll give you his contact info). It feels about the same weight as the EQ-6. The Mach-2 we don't have any experience with it.
