Lagos: The Practical Verdict

Lagos, a major city in Nigeria's Lagos State, presents considerable obstacles for stargazing due to its severe light pollution. The sky here is predominantly rated as a poor urban or suburban setting, classified as Bortle 7. This means the city lights overpower much of the celestial spectacle, rendering most deep-sky objects practically invisible.

From this level of light pollution, stargazers can realistically observe the Moon, planets, and bright double stars, as well as engage in narrowband imaging with careful processing. However, the Milky Way is not visible from Lagos. Visual deep-sky observing and broad-band galaxies are poor targets in these conditions.

For those seeking slightly darker skies, Igbin, about 20 km east, offers a modest improvement with a Bortle 6 sky. While not dramatically darker, it provides a slightly better opportunity for observation without having to undertake a much longer trip.

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

Igbin, 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 19.03, 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 19.03), 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?

No meaningfully darker mapped site was found within the search radius around Lagos.

When is the sky darkest in Lagos?

The sky over Lagos is darkest around January, December.

Is light pollution in Lagos getting better or worse?

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