18.4 million light-years (Pisces A), 29.0 million light-years (Pisces B)
Data were provided by HST proposal 13745: E. Tollerud (STScI), M. Geha (Yale University), J. Grcevich (AMNH), M. Putman (Columbia University), and D. Stern (JPL). The science team also includes D. Weisz (University of Washington) and A. Dolphin (Raytheon).
F606W (wide V), F814W (I)
These images are each composites of separate exposures acquired by the ACS/WFC instrument. Two filters were used to sample different wavelength bands. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
Cyan-blue: F606W (wide V)
Red-orange: F814W (I)
