IC 4603/4 are a pair of nebulae located in the Rho Ophiuchi cloud complex — a region known for its vivid colors in deep-sky photography. Among the typical blues of reflection nebulae are yellows caused by dust reflecting light from Antares, as well as the reds and magentas of hydrogen emission. The photographer captured this two-panel mosaic with 6.8 hours of exposure with a 12-inch f/3.6 scope.
