Valletta: The Practical Verdict

Valletta is Malta's capital and a small city on the island's north-east coast. The stargazing conditions here are characterised by high light pollution, providing a poor city sky overall. The primary limiting factor is the bright urban sky background, which erases the Milky Way completely.

Despite the heavy light pollution, some celestial targets can still be observed. The Moon, planets, and bright stars are realistically visible, along with potential double star observations or solar system events. Narrowband imaging is possible if done with care, but attempts at visual deep-sky observing or widefield Milky Way shots should be avoided due to the intense light pollution.

For those seeking marginally darker skies, travelling to Piano Alto in Sicily, to the north-north-east, offers some improvement. Although nearby darker options exist, they do not provide a dramatically better stargazing experience and will only modestly reduce the light pollution levels.

At a Glance

Overall

Poor city sky - This is a poor city sky. The Milky Way is not visible and most deep-sky observing is unrealistic from the location itself.

Milky Way

Not visible - The Milky Way is erased by the bright urban sky background.

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

Limited nearby upgrade

Piano Alto, Sicily is the strongest nearby option but remains Bortle 6; the improvement is real but modest.

Good dark window

Valletta'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 Valletta?

No. Valletta is a Bortle Class 8 sky with SQM 18.25, 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 Valletta?

Valletta is Bortle Class 8 (SQM 18.25), a poor city sky for astronomy.

Is Valletta good for stargazing?

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

Is Valletta good for astrophotography?

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

What can you observe from Valletta?

Primary targets from Valletta 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 Valletta?

The closest meaningfully darker mapped site is Għajnsielem, about 19 km west north west of Valletta, reaching Bortle 7.

When is the sky darkest in Valletta?

The sky over Valletta is darkest around January, December.

Is light pollution in Valletta getting better or worse?

Long-term light pollution over Valletta has been broadly stable across the available measurements.
