City sky
Reading: The Practical Verdict
Reading is a small city in the county of Berkshire, England, and as a result, the sky suffers from high light pollution. Observational quality is undeniably poor due to the city's brightness, with the night sky washed out to a Bortle Class 8 level, rendering the Milky Way invisible. This heavy luminance primarily stems from urban lighting and proximity to London to the east.
The bright Reading sky offers limited opportunity for deep-sky objects, but the Moon and planets stand out as the most observable targets. Bright stars and double stars are also visible, adding a bit of variety to the telescopic eyepiece. Nebulae and widefield Milky Way photography are entirely impractical without significant travel to darker skies.
Those seeking a tangible stargazing upgrade can find moderately better conditions around Bledlow-cum-Saunderton, approximately 25 km to the north north east. While not profoundly darker, this site offers a Bortle 5 sky quality, reducing some of the urban sky glow.
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
- Bledlow-cum-Saunderton is the strongest nearby option but remains Bortle 5; the improvement is real but modest.
- Moderate dark window
- Reading'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 Reading?
No. Reading is a Bortle Class 8 sky with SQM 18.66, 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 Reading?
Reading is Bortle Class 8 (SQM 18.66), a poor city sky for astronomy.
Is Reading good for stargazing?
Not for serious deep-sky observing. Reading is a poor city sky where the Moon, planets, and a handful of bright targets are the realistic options from the city itself.
Is Reading good for astrophotography?
Broadband deep-sky imaging is heavily compromised from Reading and a Bortle 4 or darker site is strongly recommended. Even narrowband imaging is difficult from Reading without careful processing.
What can you observe from Reading?
Primary targets from Reading 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 Reading?
The closest meaningfully darker mapped site is Bledlow-cum-Saunderton, about 27 km north north east of Reading, reaching Bortle 5.
When is the sky darkest in Reading?
The sky over Reading is darkest around January, December. Significant summer limitation: around 59 nights per year have no true astronomical darkness.
Is light pollution in Reading getting better or worse?
Long-term light pollution over Reading has been broadly stable across the available measurements.
north - good
The north horizon is dark. Faint stars are visible close to the ground.
north-north-east - good
The north-north-east horizon is dark. Faint stars are visible close to the ground.
north-east - good
The north-east sky is dark to the horizon. Faint targets are accessible at all elevations here.
east-north-east - good
No noticeable light pollution to the east-north-east. The sky in this direction is dark to the horizon.
east - good
No noticeable light pollution to the east. The sky in this direction is dark to the horizon.
east-south-east - fair
A trace of skyglow near the east-south-east horizon. Stars are clear throughout this direction except very close to the ground.
south-east - good
Dark horizon to the south-east. Faint stars and extended objects in this direction behave much as they do overhead.
south-south-east - good
Dark horizon to the south-south-east. Faint stars and extended objects in this direction behave much as they do overhead.
south - good
The south sky is dark to the horizon. Faint targets are accessible at all elevations here.
south-south-west - good
The south-south-west horizon is dark. Faint stars are visible close to the ground.
south-west - good
The south-west horizon is dark. Faint stars are visible close to the ground.
west-south-west - good
Dark horizon to the west-south-west. Faint stars and extended objects in this direction behave much as they do overhead.
west - good
Dark horizon to the west. Faint stars and extended objects in this direction behave much as they do overhead.
west-north-west - good
The west-north-west sky is dark to the horizon. Faint targets are accessible at all elevations here.
north-west - good
Dark sky in the north-west direction with no obvious skyglow. Suitable for faint-object work at low elevation.
north-north-west - good
The north-north-west sky is dark to the horizon. Faint targets are accessible at all elevations here.
zenith - marginal
The zenith is brighter than natural. The Milky Way cannot be seen and faint deep-sky objects are not accessible.
