The image was created from Hubble data from proposals 10483: PI: B. Reipurth (University of Hawaii) and 12326: K. Noll (Hubble Heritage Team).
WFC3/IR F110W (J), and F160W (H), ACS/WFC F658N (H-alpha), and WFC3/UVIS F814W (I)
This image is a composite of separate exposures acquired by the ACS and WFC3 instruments. Several filters were used to sample various wavelengths. 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: F814W (I)
Cyan: F658N (H-alpha)
Green: F110W (J)
Red: F160W (H)
