Sh2-301 is an emission region in Canis Major that is about 17,000 light years away. It’s rich in ionized oxygen gas, which accounts for the blue central region.
This star-forming region is sandwiched between the more popular targets Thor’s Helmet in the Canis Major constellation and the Vela Supernova remnant in the Vela constellation. So it is often overlooked and has not been the subject of much research.
