El Paso: The Practical Verdict

El Paso, situated in Texas, is a mid-size city with around 880,000 residents. Unfortunately, it suffers from severe urban sky conditions, characterised by high light pollution. As a result, the Milky Way is not visible from within the city, and deep-sky observing is significantly impaired. However, bright objects such as the Moon, planets, and double stars remain observable.

From El Paso, observers should focus on celestial bodies that are less affected by light pollution. The Moon, planets, and bright stars stand out clearly against the city's light-dominated sky. Narrowband imaging of the brightest nebulae is feasible but requires careful handling, as broadband galaxies and faint nebulae are largely compromised.

For those seeking higher quality views, Catron County in New Mexico offers a substantial upgrade in sky darkness. Located about 295 km north-west, it is worth considering for serious deep-sky observing without the hindrance of urban glow.

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

Catron County, New Mexico sits about 293 km north west and reaches Bortle 3, roughly 36x darker.

Good dark window

El Paso'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.
