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

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
