Saint Petersburg: The Practical Verdict
Saint Petersburg, a global metropolis and key region in Russia, offers challenging conditions for stargazers due to its severe urban sky. The skies here are severely polluted, with a rating of Extreme Light Pollution. Consequently, the city sky is dominated by artificial brightness.
From within the city, the Milky Way is not visible, and only the Moon, planets, and bright stars stand out against the light pollution. Observing possibilities lean heavily on brighter astronomical events and objects, such as planetary alignments or solar system phenomena. Visual deep-sky observing is all but impossible from within the city limits.
For those seeking darker skies, Purjeniemi in Leningrad Oblast, about 185 km west, offers a substantial improvement. It is well worth the drive for those serious about deep-sky observing.
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
- Purjeniemi, Leningrad Oblast sits about 185 km west and reaches Bortle 2, roughly 138x darker.
- Moderate dark window
- Saint Petersburg's limiting factor is not only light pollution. Around midsummer, Saint Petersburg 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 Saint Petersburg?
No. Saint Petersburg is a Bortle Class 9 sky with SQM 16.41, 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 Saint Petersburg?
Saint Petersburg is Bortle Class 9 (SQM 16.41), a severe urban sky for astronomy.
Is Saint Petersburg good for stargazing?
Not for serious deep-sky observing. Saint Petersburg is a severe urban sky where the Moon, planets, and a handful of bright targets are the realistic options from the city itself.
Is Saint Petersburg good for astrophotography?
Broadband deep-sky imaging is heavily compromised from Saint Petersburg and a Bortle 4 or darker site is strongly recommended. Even narrowband imaging is difficult from Saint Petersburg without careful processing.
What can you observe from Saint Petersburg?
Primary targets from Saint Petersburg 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 Saint Petersburg?
The closest meaningfully darker mapped site is ΠΡΠΈΠΌΠΎΡΡΠΊΠΎΠ΅ Π³ΠΎΡΠΎΠ΄ΡΠΊΠΎΠ΅ ΠΏΠΎΡΠ΅Π»Π΅Π½ΠΈΠ΅, Leningrad Oblast, about 82 km north west of Saint Petersburg, reaching Bortle 5.
When is the sky darkest in Saint Petersburg?
The sky over Saint Petersburg is darkest around January, December. Major high-latitude limitation: around 121 nights per year have no true astronomical darkness.
Is light pollution in Saint Petersburg getting better or worse?
Long-term light pollution over Saint Petersburg has been broadly stable across the available measurements.
north - poor
Significant glow on the north horizon. Avoid this direction for objects below 30 degrees elevation.
north-north-east - poor
Bright skyglow dominates the lower north-north-east sky. This direction is not suitable for faint-object work at low elevation.
north-east - marginal
Moderate brightening on the north-east horizon. Star counts at low elevation here are reduced.
east-north-east - marginal
The lower east-north-east sky is moderately light-polluted. Useful for bright targets above about 20 degrees only.
east - poor
A bright dome of skyglow sits on the east horizon. Faint stars are suppressed up to roughly 25 degrees elevation.
east-south-east - marginal
A soft but obvious glow marks the east-south-east horizon. The lowest 15-20 degrees of sky in this direction are degraded.
south-east - poor
The south-east horizon is bright with artificial light. Only stars brighter than magnitude 3 are visible at low elevation.
south-south-east - poor
Strong artificial brightening to the south-south-east. Faint and mid-brightness stars near the horizon are absent.
south - poor
Strong artificial brightening to the south. Faint and mid-brightness stars near the horizon are absent.
south-south-west - poor
Bright skyglow dominates the lower south-south-west sky. This direction is not suitable for faint-object work at low elevation.
south-west - poor
A bright dome of skyglow sits on the south-west horizon. Faint stars are suppressed up to roughly 25 degrees elevation.
west-south-west - marginal
Moderate brightening on the west-south-west horizon. Star counts at low elevation here are reduced.
west - fair
Subtle skyglow on the west horizon. Faint stars below about 10 degrees here are slightly suppressed.
west-north-west - marginal
A soft but obvious glow marks the west-north-west horizon. The lowest 15-20 degrees of sky in this direction are degraded.
north-west - marginal
Persistent skyglow on the north-west horizon. Faint stars near the ground in this direction are lost.
north-north-west - poor
The north-north-west horizon is bright with artificial light. Only stars brighter than magnitude 3 are visible at low elevation.
zenith - poor
Strong light pollution at the zenith. Limiting magnitude is around 3 to the unaided eye.
