All-sky astronomical map
Here is a map of the night sky for September 2021, showing constellations you can see from mid-northern latitudes such as London or New York in mid-month at 10pm local time. The night sky chart is interactive, so you can click on the settings, to the top left of the chart, to change date and time, or your latitude, to suit your own astronomical set-up. Click for details of what you can see in the night sky, including the planets, and the Moon.
Note: The sky will appear much the same from other cities at similar latitudes, such as New York, Paris and Berlin, at around 10pm local time. The sky appears the same at the start of the month an hour later and at the end of the month an hour earlier. We use Virtual Sky, a new, customizable, browser-based planetarium, courtesy of Las Cumbres Observatory Global Telescope Network.
