The double star 61 Cygni (right of centre), a double star, in Cygnus. It is also known as “The Flying Star” for its large proper motion across the sky, noted in 1792 by Piazzi. It was also the first star to have its distance measured via trigonometric parallax, be Friedrich Bessel in 1838.

Shot Nov 10, 2014 from New Mexico, with the 92mm TMB apo refractor at its native f-ratio of f/5.5 with the Hotech field flattener, and Canon 6D for a stack of 4 x 6 minute exposures at ISO 800.
