This image shows several different objects: NGC 2035, the Dragon’s Head nebula, is the greenish-white nebulosity at the left side of the image. The red “fan”-like nebula on the lower right is NGC 2014. The bluish-green round nebula close to NGC 2014 is NGC 2020, a nebula that surrounds HD 269748, a 13.1 mag Wolf Rayet star. This narrowband image has been processed coding Halpha to Red and OIII to both green and blue (white means broadband emission, as both filters get a similar image density).
