as Earth spins on its axis, the stars appear to rotate around an observatory in this well-composed image from the Canary Island of Tenerife

of course, the colorful concentric arcs traced out by the stars are really centered on the planet's North Celestial Pole

convenient for northern hemisphere astro-imagers and celestial navigators alike, bright star Polaris is near the pole and positioned in this scene to be behind the telescope dome

made with a camera fixed to a tripod, the series of over 200 stacked digital exposures spanned about 4 hours

the observatory was not operating on that clear, dark night, but that's not surprising: the dome houses the Teide Observatory's large THEMIS Solar Telescope
