Mexico City: The Practical Verdict

As a thriving global metropolis and the capital of Mexico, Mexico City offers a severe urban sky for stargazers. The extreme light pollution gives it a Bortle Class 9 rating, making it difficult to see anything beyond the brightest celestial objects. The Milky Way is completely obscured by the city lights.

The visible targets in Mexico City primarily include the Moon, planets, bright stars, and double stars, with narrowband imaging of targets possible with care. However, visual deep-sky observing and most broadband targets are not feasible due to the overwhelming sky brightness.

For those looking to escape the urban glow for deeper celestial views, San José in Puebla, located roughly east-north-east, offers a significant upgrade with its Bortle 4 sky. It's a drive that will be worthwhile for more serious astronomical observation.

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

San José, Puebla sits about 193 km east north east and reaches Bortle 4, roughly 26x darker.

Good dark window

Mexico City 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.
