Great APOD! I have to admit that I'm a sucker for naked-eye astronomical events. I've used many APODs in the past as desktop backgrounds (David Cortner's June 23'rds Transit of Venus through the clouds being a long-standing background that constantly gets praised and questioned), and shots like these make for interesting conversation pieces and functional backgrounds.
I can't come close to counting all 51, however.
