Description

Deep in the heart of the Flaming Star Nebula (IC405) is AE Auriga, a super hot O-type star. But what you might not know is that it was likely formed in the heart of the Orion complex, many light years away, and was somehow booted out some 2.5M years ago!

I knew that stars (like atoms, planets, my hairline, and everything else in the universe) are in constant motion... usually spinning around the galactic core and dragging us along with them. But sometimes weird things (like supernovae) can launch them in all directions at amazing speeds (even for a star). AE Auriga is thought to be one of these "runaway stars".

I used to think the Flaming Star Nebula was a fairly dull chunk of (mostly red) hydrogen and I'd only photographed it together with some of its more popular neighbours. A recent mono Ha test image I took turned out really well, so it made me look closer... and I'm glad I did!

Aside from the larger flame-like emission nebula that surrounds it, this central Star is also responsible for a reflection nebula within the core. At first I thought it was Oxygen gas because it was being picked up by my Oiii filter. In reality, the interstellar medium surrounding AE Aurigae is rich in carbon dust, which is acting like a sort of mirror; amplifying the natural blue glow of this massive hot star.

This is an SHO composition (with HOO stars - didn't have time for RGB yet). 12h20' of combined exposure using my 80mm refractor and ASI2600MM + 3nm filters.

Hope you enjoy it.
