Description

The central star here is Wolf-Rayet star 40, a hundred times as massive as our Sun and 30 times as hot.  Looking at the texture of the nebula, I was struck by how similar it is to WR136 AKA the Crescent nebula.  I found SII to be useful with the Crescent so I shot quite a bit of it here.  Sadly, there is little impact from the SII so I blended what I had into the Ha in Red.  Green and Blue are OIII so were have an HS-O-O mix with RGB stars.

I did find an Ha cloud in the background.  It seems unlikely to me that it would be related to the WR star though it does seem to point toward the center of the nebule.  This same structure was visible in the SII data as well.
