Messier added it to his list on Jun 1, He described it as a "nebula without star." William Herschel was the first to resolve it into stars (1784). It is 160 light years in diameter. If its stars were grains of sand, it would be 300 miles in diameter and the sand grains would be 3 miles apart! The brightest stars are red giants some 2,000 times brighter than the sun and shine at 11m (the Sun would be 19m at this distance). There are no blue giants in the cluster. On the H-R diagram, the Main Sequence turn-off point falls a little over midway down the Main Sequence (absolute magnitude +4.1), implying an age of around 10 billion years. The total mass of M13 is something like 500,000 solar masses. The brightest stars are 11.8m and the horizontal branch is 15.0m. C8 at 65x. wesome! Resolved at low power, it takes high power very well. It looks a little flat on the E side. Steve Coe mentions that three dark, thin lanes seem to trisect it into unequal thirds, giving rise to a feature called "the propellor." In a letter to stronomy Magazine, lister Ling, an amateur from Edmonton, Canada wrote, "The intersection of the Y-shape in the dark lanes is oriented at the top of the [cluster]. I ve found that spotting these lanes requires at least a 6-inch telescope and 200x... In 1855, Lord Rosse stated the lanes do not join in the center, but to the southeast. Yet observers today often mistakenly look for the dark lanes in the middle of the cluster and wonder why they can t find them." ccording to "The ackyard stronomer" column in the June 1986 stronomy, "These are not holes in the cluster but rather perceptual effects of seeing more bright stars at one place and less at another."
