Welcome to the night sky report for September 2025 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. During September, Saturn puts on a spectacular show and a sunrise conjunction shines bright as we ring in the autumnal equinox. Also this month, Pegasus becomes increasingly prominent in the southeastern sky, allowing skywatchers to locate globular clusters M2 (NGC 7089), 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, so get outside and explore its wonders from your own backyard.
