Where is horsehead nebula

Dark Nebula in Orion. Show on Sky Map. This plume of dark material makes up one of the most recognisable objects in the night sky - the Horsehead Nebula in Orion. The horsehead shape is visible against the glowing pink of the emission nebula IC The famous dark Horsehead Nebula lies in the central regions of Orion. A view of the sky around the Horsehead Nebula.

Because this area contains a lot of hydrogen gas, a narrowband h-alpha filter is an effective choice for collecting important details of this subject.

This isolates very specific areas of light emitted from the area surrounding the Horsehead Nebula and Flame Nebula. Related Article: Narrowband Imaging Basics. The image below was captured using a very modest astrophotography setup that included a Sky-Watcher Star Adventurer tracking mount.

Results using a DSLR camera and mm camera lens cropped. The entire imaging kit used for this project is rather affordable and portable. Darker skies will help produce better images using this configuration. Photos captured using a narrowband Hydrogen Alpha filter ignore almost all wavelengths of artificial light and produce a detailed monochrome portrait of the area. A filter like this is a great way to add impressive narrowband details to your existing color photos and even shoot during a full moon.

I absolutely love the way this filter isolates hydrogen gas in emission nebula targets. It also captures very small, sharp stars in a way that a broadband filter never could. As I mentioned earlier, clip-in filters like this can be used with a camera lens as well. To create the image below, I captured several 4-minute exposures totaling 1 hour and 20 minutes of overall exposure time.

This method can produce incredible portraits of deep-sky nebulae like the Horsehead Nebula, even from bright skies in the city. The image scale of this system creates an up-close view of the Horsehead Nebula at high magnification. The Horsehead Nebula is isolated from the nearby Flame Nebula for an unforgettable view. The addition of isolated H-alpha data can help boost the overall impact of your image. Williamina Fleming standing , Edward Pickering far left and a team of human "computers" cataloged and classified thousands of celestial objects in the late s, including the Horsehead Nebula.

But she was soon hired to analyze stellar spectra — the chemical fingerprints of stars. Fleming's system of classifying stars grew in popularity, and astronomers still use today. Throughout her career, Fleming cataloged thousands of objects — and one of those was the Horsehead Nebula.

In , she was reviewing one of Pickering's photographic plates when she spotted the nebulous object. To her, it was simply one more nebulae out of the myriad other objects she cataloged during her lifetime.

But, Fleming still gets credit for the first confirmed discovery of the Horsehead Nebula. But that leaves another question: Who named the Horsehead Nebula? The historical record is vague on this point. However, the latter term came to dominate soon after, as more and more astronomers were able to capture detailed photographs of it. By the dawn of the Space Race, the Horsehead Nebula was a favorite in astronomy books, magazines, and works of science-fiction.

Today, the Horsehead Nebula appears far more often in desktop wallpapers than it does in scientific papers. Space fans all over the world love the charismatic cosmic equine. And its highly doubtful that's going to change anytime soon.
