Messier 7 is a beautiful open cluster near the tip of the scorpion's tail in the constellation Scorpius. Messier 7 is estimated to be approximately 800 to 1,000 light years distant and is an easy naked eye object in relatively dark skies. This 54 minute exposure also captures multitudes of background stars and dark nebula as we look toward the center of the Milky Way galaxy.
