The colors of the Cave

Steve Leonard, taken from Markham, Ontario

The Cave Nebula (Sharpless 2–155) is an object that features emission, reflection, and dark nebulae. This Hα/OIII/SII image with exposures of 10, 13, and 6 hours, respectively, taken with a 4.5-inch refractor, was processed as a blend of a static Hubble-palette rendition and a dynamic Foraxx-palette combination of channels.
