Where is Messier 10?

Times for LondonChange city

Look southwest, about 20° up at 20:20 in Ophiuchus. It sinks lower through the evening and sets at 22:43.

From London tonight, Messier 10 is above the horizon after dark. It’s highest soon after dark, around 20:20, in the southwest at 20°.

At magnitude 5.0, with its light spread out, it needs binoculars and a dark sky.

This is position and timing only: clouds, haze and light pollution aren’t included.

Only from a very dark site, if at all: a faint smudge.

A small, fuzzy ball of light.

The edges break up into stars at medium magnification in larger telescopes.

What you’re likely to see, not what a space telescope photographs. General guidance from catalog brightness and size, not a forecast for tonight.

Messier 10 (M10) is a globular cluster in Ophiuchus, with a total brightness of magnitude 5.0 and an apparent size of 9.3′.
