Seville: The Practical Verdict

Seville, a major city in Andalusia, offers challenging conditions for stargazing due to extreme light pollution. With a Bortle Class 9 sky, it falls under "Severe urban sky", leaving very few celestial objects easily visible. A dense urban setting largely limits the potential for serious astronomical observation.

From Seville, only the Moon, planets, and the brightest stars penetrate the overwhelming light dome. The Milky Way remains entirely obscured. While narrowband imaging might succeed on the brightest nebulae with care, most deep-sky objects require darker conditions. For astrophotographers and deep-sky observers, these conditions prove far from ideal.

For improved stargazing, El Guindo in Extremadura provides a meaningful upgrade. Situated to the east south-east, around a two-hour drive from Seville, it boasts Bortle 4 skies, offering significantly better opportunities for deep-sky observing.

At a Glance

Overall
Severe urban sky - This is a severely light-polluted urban sky. Only the Moon, planets, bright stars, and a few specialist targets remain practical.
Milky Way
Not visible - The Milky Way is not visible from this sky.
Best targets from here
Moon, planets, bright stars, double stars, solar system events, narrowband imaging only with care
Do not prioritise
visual deep-sky observing, broadband galaxies, reflection nebulae, widefield Milky Way
Best nearby upgrade
El Guindo, Extremadura sits about 126 km east south east and reaches Bortle 4, roughly 30x darker.
Good dark window
Seville's longest dark windows fall in December and January, with the shortest nights around June and July. Plan deep-sky sessions around the autumn and winter months for the best combination of long nights and true astronomical darkness.

Frequently Asked Questions

Can you see the Milky Way from Seville?

No. Seville is a Bortle Class 9 sky with SQM 17.59, 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 Seville?

Seville is Bortle Class 9 (SQM 17.59), a severe urban sky for astronomy.

Is Seville good for stargazing?

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

Is Seville good for astrophotography?

Broadband deep-sky imaging is heavily compromised from Seville and a Bortle 4 or darker site is strongly recommended. Even narrowband imaging is difficult from Seville without careful processing.

What can you observe from Seville?

Primary targets from Seville include Moon, planets, bright stars, double stars, solar system events. Targets such as visual deep-sky observing, broadband galaxies, reflection nebulae are not realistic from this sky.

Where are darker skies near Seville?

The closest meaningfully darker mapped site is Aznalcázar, Andalusia, about 46 km south west of Seville, reaching Bortle 6.

When is the sky darkest in Seville?

The sky over Seville is darkest around January, December.

Is light pollution in Seville getting better or worse?

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

north - fair

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

north-north-east - fair

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

north-east - fair

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

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 - fair

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

east-south-east - marginal

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

south-east - fair

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

south-south-east - marginal

Soft skyglow visible on the south-south-east horizon. Mid-brightness stars survive at low elevation; the faintest do not.

south - fair

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

south-south-west - fair

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

south-west - fair

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

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

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

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

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

north-north-west - fair

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

zenith - poor

The zenith sky is bright. The Milky Way is absent and most constellation stars are not visible.
