Alexandria: The Practical Verdict

Alexandria, a small city in Virginia, is characterised by its suburban landscape and proximity to Washington, D.C. As a location with high light pollution, the stargazing quality here is poor, making it challenging to observe anything other than the brightest objects. The substantial light dome from Washington certainly contributes to this sky glow.

In Alexandria, the Milky Way is entirely obscured by the bright urban sky, leaving observers to focus on targets like the Moon, planets, bright stars, and double stars. For those with a keen interest, narrowband imaging demands great care to capture only the brightest nebulae. Conventional deep-sky observing or viewing nebulous objects and meteor showers is largely impractical here.

For a better stargazing experience, the site worth travelling to is Farnham, Virginia, about 110 km south-south-east. This darker location offers significantly improved conditions, suitable for serious deep-sky observation.

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

Best nearby upgrade

Farnham, Virginia sits about 109 km south south east and reaches Bortle 4, roughly 15x darker.

Good dark window

Alexandria'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 Alexandria?

No. Alexandria is a Bortle Class 8 sky with SQM 18.10, 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 Alexandria?

Alexandria is Bortle Class 8 (SQM 18.10), a poor city sky for astronomy.

Is Alexandria good for stargazing?

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

Is Alexandria good for astrophotography?

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

What can you observe from Alexandria?

Primary targets from Alexandria 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 Alexandria?

The closest meaningfully darker mapped site is Magruder Landing, Maryland, about 36 km east south east of Alexandria, reaching Bortle 6.

When is the sky darkest in Alexandria?

The sky over Alexandria is darkest around January, December.

Is light pollution in Alexandria getting better or worse?

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