Emerging like a celestial dolphin leaping through the cosmos, Sh2-308, or the Dolphin Nebula, is a striking example of a Wolf-Rayet bubble located in the Canis Major constellation. This expansive nebula spans around 60 light-years and is formed by the powerful stellar winds from a massive Wolf-Rayet star.
π Target: Sh2-308 (Dolphin Nebula)
π Location: Constellation Canis Major, approximately 4,500 light-years away
π Central Star: EZ Canis Majoris (WR 6)
π‘ Apparent Magnitude: ~12 (nebulosity)
π Apparent Size: ~40 arcminutes
About the Region:
The soft, bluish glow comes from ionized oxygen (OIII) excited by the high-energy radiation of the central Wolf-Rayet star. These rare stars are in a late evolutionary stage, ejecting intense stellar winds that sculpt the surrounding gas into this ethereal bubble-like structure.
π¨ Processing Notes:
This image highlights the delicate filamentary structure of the nebula, accentuating its ethereal quality against the backdrop of countless stars.
Instrument: Telescope Takahashi FSQ-106ED, Camera QHY 600M, Filters Astrodon Halpha, OIII, SII
Lights: Halpha 16x300", OIII 16x300", SII 16x300
