Next to the Orion Nebula, the lagoon nebula is probably the next most photographed messier object that is an emission nebula. It is a large object that is easily found in the heart of the milky way. This size and contrast with the background milky way starfield makes for spectacular images.
This wider field image was taken with the same camera and a Zenithstar 61 telescope.
