Color: This image is a composite of separate exposures acquired by the WFC3/IR instruments. Two filters were used to sample different infrared 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:
WFC3/IR F110W (YJ) cyan/blue
WFC3/IR F160W (H) red/orange
Orientation/Scale: Compass and Scale Image for Horsehead Nebula
