NGC 248, DEM S 16, SMC N13
These datasets are from the HST proposal 13659, P.I.: K. Sandstrom (University of California, San Diego).
F475W (B), F550M (narrow V), F658N (H-alpha), and F814W (i)
This image is combined from separate exposures acquired by HST's ACS/WFC instrument. Four 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:
Blue: F475W (B)
Green: F550M (narrow V)
Orange: F658N (H-alpha)
Red: F814W (i)
