Edmonton: The Practical Verdict

Edmonton, the bustling capital city of Alberta, exhibits a severe urban sky that falls under Extreme Light Pollution. Stargazing enthusiasts in the city will find the conditions challenging, with the Milky Way entirely obscured from view. This is due to the intense light pollution that blankets the area, restricting any chance of seeing deep-sky objects.

From within Edmonton's city limits, practical observation targets include the Moon, planets, bright stars, and double stars. More ambitious imaging should focus on narrowband techniques, but even then, it’s best approached with caution given the pervasive sky-glow. Amateur astronomers aiming for bright nebulae are likely to find them only marginally visible if at all under such conditions.

For those willing to venture further, Improvement District No. 12 in Alberta offers a significant upgrade. Located about 255 km to the west-south-west, it features a Bortle Class 3 sky well worth the longer drive if you're after serious deep-sky exploration.

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

Improvement District No. 12, Alberta sits about 253 km west south west and reaches Bortle 3, roughly 45x darker.

Moderate dark window

Edmonton's limiting factor is not only light pollution. Around midsummer, Edmonton loses true astronomical darkness entirely, so deep-sky observing and imaging are strongly seasonal. Plan serious sessions around the darker months.

Frequently Asked Questions

Can you see the Milky Way from Edmonton?

No. Edmonton is a Bortle Class 9 sky with SQM 17.52, 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 Edmonton?

Edmonton is Bortle Class 9 (SQM 17.52), a severe urban sky for astronomy.

Is Edmonton good for stargazing?

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

Is Edmonton good for astrophotography?

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

What can you observe from Edmonton?

Primary targets from Edmonton 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 Edmonton?

The closest meaningfully darker mapped site is Improvement District No. 12, Alberta, about 253 km west south west of Edmonton, reaching Bortle 3.

When is the sky darkest in Edmonton?

The sky over Edmonton is darkest around January, December. Significant summer limitation: around 78 nights per year have no true astronomical darkness.

Is light pollution in Edmonton getting better or worse?

There is not yet enough long-term data to give a confident trend for Edmonton.
