Suburban/urban transition

Launceston: The Practical Verdict

Launceston, a small city in Tasmania, lies on the suburban spectrum with high light pollution. Overall, it offers a poor urban/suburban sky. The primary constraint here is the substantial light pollution, making it challenging for most celestial targets.

The heavy light pollution means the Milky Way isn't realistically visible from Launceston. Observing is centred on the Moon, planets, bright double stars, and bright open clusters. Narrowband imaging of bright nebulae can be effective with careful processing, but visual observation of deep-sky objects is generally impractical. Avoid attempting broadband galaxy photography or faint meteor work.

For deeper-sky pursuits, Legerwood in Tasmania, around a two-hour drive to the north-east, provides a much darker backdrop. Heading there rewards you with an environment more conducive to serious stargazing.

At a Glance

Overall

Poor urban/suburban sky - This is a poor sky for astronomy. The Moon, planets, and a few bright objects remain viable, but deep-sky work is difficult.

Milky Way

Not visible - The Milky Way is not realistically visible from this level of light pollution.

Best targets from here

Moon, planets, bright double stars, bright open clusters, narrowband imaging with careful processing

Do not prioritise

visual deep-sky observing, broadband galaxies, reflection nebulae, Milky Way photography

Best nearby upgrade

Legerwood, Tasmania sits about 57 km north east and reaches Bortle 2, roughly 11x darker.

Good dark window

Launceston's longest dark windows fall in June and July, with the shortest nights around December and January. For deep-sky imaging, winter gives the best combination of long nights and true astronomical darkness.

Frequently Asked Questions

Can you see the Milky Way from Launceston?

No. Launceston is a Bortle Class 7 sky with SQM 19.15, 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 Launceston?

Launceston is Bortle Class 7 (SQM 19.15), a poor urban/suburban sky for astronomy.

Is Launceston good for stargazing?

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

Is Launceston good for astrophotography?

Broadband deep-sky imaging is heavily compromised from Launceston and a Bortle 4 or darker site is strongly recommended. Narrowband imaging of bright emission nebulae remains viable from Launceston with appropriate Ha or OIII filters.

What can you observe from Launceston?

Primary targets from Launceston include Moon, planets, bright double stars, bright open clusters, narrowband imaging with careful processing. Targets such as visual deep-sky observing, broadband galaxies, reflection nebulae are not realistic from this sky.

Where are darker skies near Launceston?

The closest meaningfully darker mapped site is Retreat, Tasmania, about 26 km south of Launceston, reaching Bortle 3.

When is the sky darkest in Launceston?

The sky over Launceston is darkest around June, July.

Is light pollution in Launceston getting better or worse?

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