Las Vegas: The Practical Verdict

Las Vegas, a major city in Nevada, is a location dominated by severe light pollution, classified under Extreme Light Pollution conditions. Stargazing here is very challenging due to the urban sky's brightness, which severely limits the visibility of most celestial targets.

The Milky Way is not visible, and stargazers will largely need to focus on the Moon, planets, and bright stars. Narrowband imaging of the brightest nebulae is possible but only with care. Attempting to view reflection nebulae or faint galaxies is futile under this sky.

For serious stargazing, consider travelling to Nye County, Nevada, situated to the north-west. This location offers significantly darker skies, making it worthwhile for those seeking to observe deep-sky objects.

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

Nye County, Nevada sits about 275 km north west and reaches Bortle 3, roughly 71x darker.

Good dark window

Las Vegas'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 Las Vegas?

No. Las Vegas is a Bortle Class 9 sky with SQM 16.91, 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 Las Vegas?
