I have three other versions of this image (HaRGB, LHaRGB, and a starless variant) of this image due to just having some fun and enjoying the different ways to process NBLRGB data sets. You can find all 4 versions of the image on the link above. I wish Reddit let me post albums! Imgur compression is just too bad to use.
Thanks for looking!
If you feel like looking at some of my other images or following me on social media, here is a shameless plug:
Is star AE Aurigae on fire? No. Even though AE Aurigae is named the flaming star, the surrounding nebula IC 405 is named the Flaming Star Nebula, and the region appears to have the color of fire, there is no fire. Fire, typically defined as the rapid molecular acquisition of oxygen, happens only when sufficient oxygen is present and is not important in such high-energy, low-oxygen environments such as stars. The material that appears as smoke is mostly interstellar hydrogen, but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae, visible toward the right near the nebula's center, is so hot it is blue, emitting light so energetic it knocks electrons away from surrounding gas. When a proton recaptures an electron, light is emitted, as seen in the surrounding emission nebula. Pictured above, the Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga).

Wallpaper material right there. Its so beautiful. Amazing work!

I'm not familiar with astrophotography, but how do you expose 17 hours and not be overexposed by sunlight?
