NGC 6726/6727 and IC 4812 are blue reflection nebulae, where bright stars are embedded in a large cloud of dust which reflects the blue light of the stars. NGC 6729 is a butterfly-shaped emission/reflection object that is a variable nebula, powered by the irregular variable star, R Coronae Australis (R CrA). R CrA was discovered about 100 years ago. HH objects are shown as delicate, small arcs of glowing gas.
