How dark the sky is at Steens Mountain: Bortle Class 1, excellent dark-sky site

The zenith sky here reads 22.00 magnitudes per square arcsecond. That is as dark as a natural sky gets: almost all the glow comes from airglow and starlight, not lamps.

Milky Way

The Milky Way casts faint shadows; the Scorpius and Sagittarius star clouds show structure to the naked eye

Zodiacal light

Zodiacal light, the gegenschein and the zodiacal band are all visible

Faintest naked-eye stars

Magnitude 7.6 to 8.0 overhead

Naked eye

M33 is a direct-vision naked-eye object; airglow makes the sky faintly green near the horizon

At the eyepiece

Galaxies to magnitude 14 and fainter show in a 200 mm telescope; the limit is your eye, not the sky

1 mag 8.0 21.99+ 2 mag 7.5 21.89+ 3 mag 7.0 21.69+ 4 mag 6.5 20.49+ 5 mag 6.0 19.50+ 6 mag 5.5 18.94+ 7 mag 5.0 18.38+ 8 mag 4.5 18.00+ 9 mag 4.0
The Bortle scale. Each panel shows the class number, the faintest star the naked eye reaches at the zenith, and the darkest-edge sky brightness reading of that class in mag/arcsec².

Sky brightness and class come from the World Atlas of Artificial Night Sky Brightness (Falchi et al. 2016, CC BY-NC 4.0), with natural skyglow added. On the night, haze, smoke, humidity and the Moon set the real limit; see every Bortle Class 1 place.
