The Hubble community bids farewell to the soon-to-be decommissioned Wide Field Planetary Camera 2 (WFPC2) onboard the Hubble Space Telescope. In tribute to Hubble's longest-running optical camera, planetary nebula K 4-55 has been imaged as WFPC2's final "pretty picture."

The image was created from Hubble data from proposal 11956: K. Noll, Z. Levay, M. Mutchler, L. Frattare, M. Livio, W. Januszewski, C. Christian, F. Hamilton, and H. Bond (Hubble Heritage Team/STScI). R. Sahai and J. Trauger (JPL) consulted on the target.

The image is a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
