With every passing hour our solar system comes forty-three thousand miles closer to globular cluster 13 in the constellation Hercules, and still there are some misfits who continue to insist that there is no such thing as progress.

Faint, lonesome red variable star with a touch of orange. Two fairly bright stars located nearby to the W and NW, making a nice triangle with AX CYG. To the NE (outside this FoV) there's a binary that looks colourful too. Despite its faintness it is a very remarkable view.
