Position (J2000): R.A. 01h 29m 31s
Dec. -73° 33' 15"
Constellation: Tucana

About the Data
Data Description: The Hubble image was created from HST data from proposal 10248: A. Nota (STScI/ESA), M. Sirianni (STScI/ESA), E. Sabbi (University of Bologna), M. Tosi (INAF - Bologna Observ.), J. Gallagher (University of Wisconsin), M. Meixner (STScI), M. Clampin (Goddard Space Flight Center), S. Oey (University of Michigan), A. Pasquali (ETH, Zurich), L. Smith (University College London), and R. Walterbos (New Mexico State University). The science team also includes L. Carlson (Johns Hopkins University).
Instrument: ACS/WFC
Exposure Date(s): July 14/18, 2004
Filters: F555W (V), F658N (Halpha+[N II]), and F814W (I)
About the Image
Image Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA) - ESA/Hubble Collaboration
Release Date: January 8, 2007
Color:

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Two filters were used to sample broad wavelength ranges. One filter was used to sample narrow wavelength emission. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F555W (V) blue
F555W (V) + F814W (I) green
F658N (Halpha+[N II]) + F814W (I) red
