Thank you for looking at Sh2-308. Ha, OIII and RGB.
Also designated as Sharpless 308, RCW 11, or LBN 1052, is an emission nebula and HII region located near the center of the constellation Canis Major, composed of ionized hydrogen. It is about 8 degrees south of Sirius, the brightest star in the night sky.
This wonderful data set comes from team Chilescope and demonstrate the capability of great optics located under true clear skies. Well done team! I had an enjoyable time processing this data. Keep up the good work Team Chilescope
