Bond Space Telescope Science Institute CoI: Keith Noll Space Telescope Science Institute N CoI: Anne Kinney Space Telescope Science Institute N CoI: Carol Christian Space Telescope Science Institute N Observations Description ------------------------ We are observing the Ring Nebula (NGC 6720) as part of the Hubble Heritage Program, aimed at providing spectacular HST images for public release, outreach, and education. A color image of the Ring will be made by observing in narrow-band filters isolating the He II, [O III], and [N II] lines (filters F469N, F502N, F658N). Due to the large size of the nebula, it is covered by taking exposures at two different pointings.
