Welcome to the night sky report for September 2020 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. In September, Pegasus becomes increasingly prominent in the southeastern sky, allowing stargazers to locate globular clusters M2 (NGC 7089) and M30 (NGC 7099), as well as a nearby double star, Alpha Capricorni, which is an optical double (but not a binary pair). The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.
