This is a beautiful image! Thanks Dieter.
This past weekend I was leading a skywatching weekend at Wilbur Hot Springs in Colusa County, northern California, where we were blessed with a clear dark sky. M7 was popular. Folks enjoyed comparing how this cluster and the milky way background look to the naked eye, through binoculars, and through an 8-inch telescope at 50x magnification. The fact that these stars are "only" a couple of hundred million years old raised a few eyebrows, and led to an interesting discussion of the life cycles of stars. So it's a pleasant memento to see this lovely picture.
