IC405 Flaming Tar Nebula in Auriga

November 9, 2015

Last night was another one of those glorious fall nights, with mild temps and an occasional brilliant Taurid meteor streaking overhead. I would have stayed up imaging even longer except for some high smoke that drifted in from a controlled burn somewhere near Flagstaff. Once again I had fun with my friend Bill Burke's excellent vintage 6-inch Astro Physics refractor, with it's outstanding contrast and sharp optics.

This object, IC-405 aka The Flaming Star Nebula in Auriga, is one of my favorite and most beautiful star emission and reflection nebulae. This image is a composite of 3 x 5 minute exposures with the Canon 6D shooting at ISO 6400 and an IDAS LpS-V4 filter. It was then combined with an earlier image taken with my TMB-130 refractor with the same camera and filter. Cumulative exposure is bout 30 minutes.

The Flame Nebula

"The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula in the constellation Orion. It is about 900 to 1,500 light-years away.

The bright star Alnitak (ζ Ori), the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electrons away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electrons and ionized hydrogen recombine. Additional dark gas and dust lies in front of the bright part of the nebula and this is what causes the dark network that appears in the center of the glowing gas. The Flame Nebula is part of the Orion Molecular Cloud Complex, a star-forming region that includes the famous Horsehead Nebula."
