Pismis 24 Star Cluster

About the colours

This image is a composite of many separate exposures made by the ACS and WFPC2 instruments on the Hubble Space Telescope using several different filters. Five filters were used to sample both broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F550W (V) + F547M (Strömgren y) Red: F656N (Halpha) + F658N (Halpha+[N II]) + F850LP (SDSS i)
