The nebula itself is only a portion of much larger spherical structure of material ejected during ancient supernova explosion. All exposures were performed through narrow-band filers to enhance only particular wavelengths, on which the interstellar gaseous clouds shine.

Thomas used his G2-4000 CCD camera for imaging and G1-0301 camera for guiding of the ASA 10” corrected Newtonian telescope. Total exposure time is 80 hours (20 hours were needed for each field).
