Lagos: The Practical Verdict

Lagos is a vast metropolitan area in Nigeria characterised by intense urban lighting and dense development. The overall sky quality from within the city itself remains poor for astronomy, dominated by high light pollution levels.

The Milky Way is completely absent, overwhelmed by the brightness of the surroundings. Observers can still enjoy visual targets such as the Moon and planets, bright double stars, and attempts to observe emission nebulae using narrowband filters. However, broadband astrophotography and faint deep-sky targets should be avoided.

Nearby locations, such as Arapagi eastward about 40 km away, offer slightly darker conditions but only modest improvements. For significant upgrades in sky darkness, travelling towards regions around 300 km south-west is necessary.

At a Glance

Overall
Poor urban/suburban sky - This is a poor sky for astronomy. The Moon, planets, and a few bright objects remain viable, but deep-sky work is difficult.
Milky Way
Not visible - The Milky Way is not realistically visible from this level of light pollution.
Best targets from here
Moon, planets, bright double stars, bright open clusters, narrowband imaging with careful processing
Do not prioritise
visual deep-sky observing, broadband galaxies, reflection nebulae, Milky Way photography
Limited nearby upgrade
Arapagi, Lagos State is the strongest nearby option but remains Bortle 6; the improvement is real but modest.
Good dark window
Lagos retains astronomical darkness throughout the year, so seasonality is less extreme than at higher latitudes. The main limitation is light pollution, not the length of the dark window.

Frequently Asked Questions

Can you see the Milky Way from Lagos?

No. Lagos is a Bortle Class 7 sky with SQM 18.91, so the Milky Way is not visible from the city. For Milky Way photography, look for a Bortle 4 or darker site.

What Bortle class is Lagos?

Lagos is Bortle Class 7 (SQM 18.91), a poor urban/suburban sky for astronomy.

Is Lagos good for stargazing?

Not for serious deep-sky observing. Lagos is a poor urban/suburban sky where the Moon, planets, and a handful of bright targets are the realistic options from the city itself.

Is Lagos good for astrophotography?

Broadband deep-sky imaging is heavily compromised from Lagos and a Bortle 4 or darker site is strongly recommended. Narrowband imaging of bright emission nebulae remains viable from Lagos with appropriate Ha or OIII filters.

What can you observe from Lagos?

Primary targets from Lagos include Moon, planets, bright double stars, bright open clusters, narrowband imaging with careful processing. Targets such as visual deep-sky observing, broadband galaxies, reflection nebulae are not realistic from this sky.

Where are darker skies near Lagos?

The closest meaningfully darker mapped site is Igbede, Lagos State, about 25 km west south west of Lagos, reaching Bortle 6.

When is the sky darkest in Lagos?

The sky over Lagos is darkest around January, November.

Is light pollution in Lagos getting better or worse?

There is not yet enough long-term data to give a confident trend for Lagos.

north - fair

Faint glow on the north horizon. Most stars are visible to low elevation; only the faintest near the ground are affected.

north-north-east - fair

A faint diffuse glow on the north-north-east horizon. Stars are visible to low elevation, with minor losses near the ground.

north-east - fair

Light glow detectable on the north-east horizon. The effect fades quickly with elevation and does not affect overhead work.

east-north-east - fair

A trace of skyglow near the east-north-east horizon. Stars are clear throughout this direction except very close to the ground.

east - good

No noticeable light pollution to the east. The sky in this direction is dark to the horizon.

east-south-east - fair

Light glow detectable on the east-south-east horizon. The effect fades quickly with elevation and does not affect overhead work.

south-east - marginal

A diffuse glow sits on the south-east horizon. Faint objects below 20 degrees in this direction are compromised.

south-south-east - fair

The south-south-east sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.

south - fair

A trace of skyglow near the south horizon. Stars are clear throughout this direction except very close to the ground.

south-south-west - fair

A faint diffuse glow on the south-south-west horizon. Stars are visible to low elevation, with minor losses near the ground.

south-west - fair

A faint diffuse glow on the south-west horizon. Stars are visible to low elevation, with minor losses near the ground.

west-south-west - fair

Faint glow on the west-south-west horizon. Most stars are visible to low elevation; only the faintest near the ground are affected.

west - fair

Light glow detectable on the west horizon. The effect fades quickly with elevation and does not affect overhead work.

west-north-west - fair

The west-north-west sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.

north-west - fair

Faint glow on the north-west horizon. Most stars are visible to low elevation; only the faintest near the ground are affected.

north-north-west - fair

Light glow detectable on the north-north-west horizon. The effect fades quickly with elevation and does not affect overhead work.

zenith - marginal

The zenith sky is noticeably bright. Only the brighter members of each constellation are visible.
