M13 in the constellation Hercules
- M13 – First discovered by Edmond Halley (of Halley’s Comet fame) in 1714, and one of the oldest and most densely populated globular clusters with nearly one million stars.
- M15 – 32000 light years distant, may have a 4000 solar mass black hole at its core.
- M3 – First discovered by Charles Messier in May 1764. Thought to contain over 500,000 stars, and is 190 light years across.
- M80 – Several hundred thousand stars, 32000 light years distant, and one of the densest clusters.
- Three planets are visible in the sky tonight- Mercury, Jupiter and Saturn (Mercury sets very early, shortly after dusk).
- Unlike most deep sky objects, all of the globular clusters listed above are visible through both telescopes and binoculars. Please feel free to bring a personal pair of binoculars to tonight’s workshop.
- If you arrive by car, please park by 8:10 PM. Bring a chair if you can. Our presentation will start about 8:30, and observing at 9:15.
