Description

It's always interesting to see the three images that go into the making of the Hubble Palette RGB image. Here you see the three NB images, each surrounded by the color they represent in the final image in the upper right panel. This object is unusual in that the O3 emissions is over two-times stronger than the H-alpha emission. This is reflected in the final image where blue is represented by the O3 emission and is the dominant color.
