  <pre>Hubble Photographs a Planetary Nebula to Commemorate Decommissioning of Super Camera May 10, 2009: 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." About the Object Object Name: PN K 4-55, Kohoutek 4-55, PN G084.2+01.0 Object Description: Planetary Nebula Position (J2000): R.A. 20h 45m 10s.02 Dec. +44° 39' 14".58 Constellation: Cygnus Distance: 4,600 light-years (1.4 kiloparsecs) Dimensions: This image is roughly 61 arcseconds (1.5 light-years or 0.47 parsec) wide. About the Data Data Description: 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. Instrument: WFPC2 Exposure Date(s): May 4, 2009 Exposure Time: 2 hours Filters: F502N ([O III]), F656N (H-alpha), and F658N ([N II]) About the Image Image Credit: NASA, ESA, and the Hubble Heritage Team (STScI/NASA) Release Date: May 10, 2009 Color: 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: F658N ([N II]) red F656N (H-alpha) green F502N ([O III]) blue </pre>
