This image contains digital watermarking or credits in the image itself. The usage of visible watermarks is discouraged. If a non-watermarked version of the image is available, please upload it under the same file name and then remove this template. Ensure that removed information is present in the image description page and replace this template with {{Metadata from image}} or {{Attribution metadata from licensed image}}.

Caution: Before removing a watermark from a copyrighted image, please read the WMF's analysis of the legal ramifications of doing so, as well as Commons' proposed policy regarding watermarks.

If the old version is still useful, for example if removing the watermark damages the image significantly, upload the new version under a different title so that both can be used. After uploading the non-watermarked version, replace this template with {{Superseded|new filename|version without watermarks}}.

Summary

[edit]
Description
English: As the name implies, this reflection nebula associated with the star Rigel looks suspiciously like a fairytale crone. Formally known as IC 2118 in the constellation Orion, the Witch Head Nebula glows primarily by light reflected from the star. The color of this very blue nebula is caused not only by blue color of its star, but also because the dust grains reflect blue light more efficiently than red. A similar physical process causes Earth’s daytime sky to appear blue. (ref: NASA) Tech Specs: William Optics REDCAT 51 Telescope, ZWO ASI071MC camera running at -10F, just over 7 hours of collected data using 60 second exposures, Sky-Watcher EQ6R-Pro mount, ZWO EAF and ASIAir Pro, processed in PixInsight. Image Date: February 5 and 6, 2024. Location: The Dark Side Observatory (W59), Weatherly, PA, USA (Bortle Class 4).
