Bortle 2: truly dark sky. Tonight's real sky above it, live.
Calculating the sky…
Drag to turn round. Stars from the HYG catalogue; glow and horizon from the light model and the terrain.
The usual sky here
Bortle 2.
The Milky Way is detailed to the horizon, with its dark lanes; clouds are black holes in the starfield.
Our own rating, from verifiable data only: sky brightness (60 points), clear nights (25), open horizon (10) and altitude (5).

Where the light comes from
The brightest glow on the horizon comes from Kaohsiung, 140 km to the north-west.
Each wedge is how much artificial light arrives from that direction (10° slices).
An estimate of the usual sky with no Moon and no clouds, from NASA's night-lights map and a light-propagation model (about ±0.3 mag). A given night depends on the Moon, the clouds, dust and humidity.

The place
Orchid Island.
Volcanic island in the Pacific Ocean part of Taiwan
Orchid Island is an island in Taiwan, 185 m above the sea.
Its usual sky, with no Moon or clouds, is estimated at 21.69 mag/arcsec² — Bortle 2, truly dark sky: the naked eye reaches stars of magnitude 6.5.
The nearest town of over 50,000 people is 88 km away.
The best months are from July to September: long dark nights and clearer skies.
The core of the Milky Way rises up to 39° above the horizon, and is up during the dark hours from March to September.
The relief hides 17% of the sky; the highest point of the horizon is 24° up, to the north.
