Description

Continuing my journey through the Sharpless catalogue, found this rarely imaged little gem. Its situated about as far away from Earth as the Dragon's of Ara nebula at ~4,300 light years.

Sh2-3/RCW120 is an emission nebula in Scorpius, with the sometimes used common name of 'Green Ring Nebula' following observations by Herschel and Spitzer showing a distinct ring in IR wavelengths. Papers published after the Herschel observations say the central star will soon (couple hundred thousand years) become one of the brightest stars in our galaxy!

Pretty light integration, but left my run on this one too late in the season as it sets pretty early in the evening from my location.  That, and clouds.  Always clouds.
