The object listed as Sh2-229 in the Sharpless catalog is the Flaming Star Nebula. It is also known as IC 405 or Caldwell 31. It is a combination emission and reflection nebula located in the constellation Auriga. The nebula surrounds the hot, bluish, irregular variable star AE Aurigae. This massive O-type star (about 23 solar masses) is responsible for illuminating the surrounding gas and dust.
Sh2-229 displays both emission (reddish glow from ionized hydrogen gas) and reflection (bluish cast from dust scattering starlight) properties. The “flaming” appearance is largely due to the bright red hydrogen emission.
I captured 166 240s subframes from my driveway. I used a Skywatcher Eq6r Pro mount, a Skywatcher Esprit 120ED telescope, and an ASI2600MC Pro camera cooled to 15f. APT was used for session management and automation. PixInsight was used to calibrate, align, integrate and process the image.
