Hi Guys
A really dim one, hence the long exposure.
Big
here
About 7,500 light years distant in the southern constellation of Carina surrounded by a perfectly circular bubble about 8’ in apparent diameter.
The gas bubble is ionized from the ultraviolet radiation of the hot WR star and glows based on its elemental makeup.
As the bubble has no significant emission of OIII and SII, this image is a blend of Ha and NII.
Ha,Ha,synthetic Green,NII mapped as LRGB. Ha 60 hrs, NII 19hrs hrs all 40min subs RGB stars 1 hr.
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
