Local sky character in San Pedro de Cajas
Tropical / equatorial latitudes · southern hemisphere · 4022 m elevation
- The south celestial pole stands 11.3° above the horizon, so stars within 11° of it never set from here.
- About 59.8% 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 72.3° up, passing almost directly overhead.
- The Large Magellanic Cloud only reaches about 31.6° altitude, so it is a low, seasonal target rather than a year-round one.
- At 4022 m elevation, roughly 38% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
San Pedro de Cajas is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
