Instrument: ACS/WFC Exposure Date(s): March and April, 2005 Exposure Time: 4.7 days Filters: F606W("V") and F814W("I") About the Image Image Credit: NASA, ESA, and H. Richer (University of British Columbia) Release Date: August 17, 2006 Color This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Three filters sample broad wavelength ranges, one isolates the light of hydrogen. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: F814W ("I") red F606W ("V") blue Orientation/Scale: Globular Cluster NGC 6397 [ http://imgsrc.hubblesite.org/hu/db/2006/37/images/b/formats/compass_large_web.jpg ] *News Release Number:*: STScI-2006-37g
