| About The Image | |
| Color Info | 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: Blue: ACS/WFC F435W (B) + F475W (g) + F555W (V) Green: ACS/WFC F606W (V) + F625W (r) + F775W (I) + Red: ACS/WFC F814W (I) + F850LP (z) + WFC3/IR F105W (Y) + F110W (YJ) + F125W (J) + F140W (JH) + F160W(H) |
