One of my better images of this rich Milky Way area containing the Trifid and Lagoon Nebulae. Shooting in the middle of summer is always tough, but I got a break when I took these some time in July of 2007.
Back when the southern sky was still dark enough to shoot long exposures, I managed to do 3 minute subs at F/2.8 and ISO 400 speeds. Taken sometime in July of 2007.
