Local sky character in Altar
Northern mid-latitudes · northern hemisphere · 414 m elevation
- The north celestial pole stands 30.7° above the horizon, so stars within 31° of it never set from here.
- About 75.5% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 30.3° up, staying low, so a clear southern horizon matters.
- At 414 m elevation, roughly 5% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Altar is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
