What you can realistically see from the city
- The Moon and the bright planets (Venus, Jupiter, Saturn, Mars when it is close) show up even from a light-polluted centre on a clear night.
- Bright stars and constellations are easy. Through binoculars, the Pleiades and the Orion Nebula (winter) still stand out; faint galaxies do not.
Darkness through the year
- From about 19 May to 23 July the sun never gets 18° below the horizon, so the sky never becomes fully dark, even at 2 a.m.
- Around the winter solstice you get about 12.1 hours of full darkness.
- Nights with 9+ hours of full darkness: October – February.
- The bright core of the Milky Way (in Sagittarius) never climbs more than 9° above the southern horizon from Cambridge, so it hides behind haze and buildings.
- The summer Milky Way through Cygnus is the one to look for: its brightest star, Deneb, passes 83° high.
