The summer stars linger longer in the sky and the moon skims the western Horizon. This year most of the brighter planets are in the morning skies. Saturn is really a highlight, as it dominates the central sky, appearing edge on
Evening Sky: In September 2025 the evening starts off with a chance to view the wonders of the Milky Way, starting from Scorpion and Saggitarius and then following it North through Aquilla, then Cygnus and Lyra, and the summer triangle
Saturn: This summer the Rings of Saturn appear edge on, this is an event that happens every 13 to 15 years. This started in March, just as Saturn moved into conjunction with sun. Saturn rises earlier in the evening now, and by late evening it is well placed to look at and enjoy this edge on view of its rings, a rare sight. Saturn is at Opposition mid-month and is brightest and closest to Earth. Below is an image from last year courtesy of Damian Peach
