What you will see
It is one of the few galaxies you can see with your eyes alone, as a milky blur. Britannica
On clear, dark nights it shows faintly as a hazy patch; binoculars or a small telescope reveal its bright core and glow. Royal Observatory, Feb 2026
Through binoculars it looks like a lens-shaped smudge. Royal Observatory, closest
EarthSky adds that most people will need binoculars or a telescope to find it. EarthSky
How bright is it? Sources differ
Lower numbers mean brighter. Because Andromeda’s light is spread over a large patch of sky, it looks fainter than a star of the same magnitude.
How to find it
- November and December are excellent months to look: after dark, the constellation is already high in the east. EarthSky
- The W-shaped constellation Cassiopeia points towards Andromeda. EarthSky
- Use the right-hand V of the W as an arrow: the galaxy is a little over 15 degrees from its tip, and a bit to the right. EarthSky
- 15 degrees is about the span of your index finger to little finger, held at arm’s length. EarthSky
- Andromeda the constellation sits next to the Great Square of Pegasus; one of the square’s stars belongs to it. EarthSky
How to look
- Give your eyes 15 minutes to adapt to the dark, and don’t look at your phone. Royal Observatory, Feb 2026
- If you use a star app, switch on its red night-vision mode. Royal Observatory, Feb 2026
- Full Moonlight counts as light pollution for the fainter sights. Royal Observatory, naked eye
