M13 was discovered by Edmond Halley in 1714, and cataloged by Charles Messier on June 1, 1764 into his list of objects not to mistake for comets; Messier’s list, including Messier 13, eventually became known as the Messier Catalog. About one third of the way from Vega to Arcturus, four bright stars in Herculēs form the Keystone asterism, the broad torso of the hero. In this M13 can be seen 2⁄3 of the way, north (by west) from Zeta to Eta Herculis. Although only telescopes with great […]

The Pleiades star cluster, also known as the Seven Sisters and Messier 45, is a conspicuous object in the night sky with a prominent place in ancient mythology. The cluster contains hundreds of stars, of which only a handful are commonly visible to the unaided eye. The stars in the Pleiades are thought to have formed together around 100 million years ago, making them 1/50th the age of our sun, and they lie some 130 parsecs (425 light years) away Location My Photo Acquisition 12×2′ light frames 10 dark frames 50 offset frames […]

This is an image of star trails that I took from my house. You can see how the stars move across the sky in a space of just 45 minutes! The point that the stars circle around points directly to the north — that is the location of the north star. Acquisition 30×90 sec exposures (total of 45 minutes) 200 ISO F/2.1 35mm zoom Processing Stacked the photos in Deep Sky Stacker Auto Histogram Stretch in Gimp Denoise in gimp Slight crop
