Burlington: The Practical Verdict

Burlington, a small city in Ontario, finds itself under a sky with high light pollution. The overall quality of astronomy here is poor, particularly affecting deep-sky observations. The main culprit is the city sky glow, which erases the Milky Way completely.

From this urban location, your best observations will be of bright objects such as the Moon, planets, and double stars. Narrowband imaging can be attempted with care, but most visual deep-sky observing and broadband imaging will struggle against the bright background. The eastern horizon offers slightly better conditions compared to the brighter north-north-east.

While there are some nearby sites like Cockshutt Road, Ontario to the south-west, offering modest improvements in sky darkness, significant upgrades require longer travel. Thus, focusing on bright targets within the city remains the most practical approach in Burlington.

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

Limited nearby upgrade

Cockshutt Road, Ontario is the strongest nearby option but remains Bortle 6; the improvement is real but modest.

Good dark window

Burlington'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 Burlington?

No. Burlington is a Bortle Class 8 sky with SQM 18.51, 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 Burlington?

Burlington is Bortle Class 8 (SQM 18.51), a poor city sky for astronomy.

Is Burlington good for stargazing?

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

Is Burlington good for astrophotography?

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

What can you observe from Burlington?

Primary targets from Burlington 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 Burlington?

The closest meaningfully darker mapped site is Moffat, Ontario, about 26 km north west of Burlington, reaching Bortle 6.

When is the sky darkest in Burlington?

The sky over Burlington is darkest around January, December.

Is light pollution in Burlington getting better or worse?
