Two Crowns

 The constellation Corona Australis (Southern Crown) lies below Sagittarius and east of the Milky Way.  At the latitude of Creede it rides close to the southern horizon.

 The constellation Corona Borealis (Northern Crown) is a well-known asterism in the northern sky.  At this time of year it can be seen above Arcturus in the west as twilight ends.

Fomalhaut rising over Snowshoe Mountain.  Sigma 56mm.

Fomalhaut (Alpha Piscis Austrini) is the 18th brightest star in the night sky and is sometimes called the "Loneliest Star" because of its large separation from other bright stars.

The sky brightness this evening was a disappointing sqml=21.25.  Red airglow is very prominent in the raw photos.
