Unique 115-hour exposure image of the Horsehead Nebula

Astrophotographer Greg Meyer has unveiled a stunning image of one of the night sky's most famous objects: the Horsehead Nebula (Barnard 33). Located approximately 1,600 light-years from Earth in the Orion constellation, this dark nebula gets its name from its unique silhouette resembling a chess knight. The image clearly shows dense clouds of gas and cosmic dust against the bright radiation of ionized hydrogen. This is reported by Ixbt.com reports .

To create this unique shot, the imaging process lasted nearly half a year—from November 2025 to March 2026, when Orion is best visible in the Arizona sky. To achieve the final result, Meyer accumulated a total exposure time of 115 hours and processed thousands of images using PixInsight, Photoshop, and Lightroom. The photographer managed to manually combine and stack the massive amount of data.

Meyer abandoned standard processing methods, combining several popular astronomical color palettes and adjusting the shadows himself. "I really dove into this process. I love this color combination enriched with complementary colors," the author said in an interview with Space.com. The image details not only the Horsehead but also other significant cosmic objects.

To the left of the silhouette lies the Flame Nebula (NGC 2024), illuminated by Alnitak, the easternmost star in Orion's Belt. In the upper left part of the frame, Alnilam, the central luminary of the "hunter's belt," glows in blue-white. It is worth noting that the Horsehead Nebula has previously been studied by powerful space telescopes like Hubble and James Webb, helping scientists unlock the secrets of star formation.
