Local sky character in Caguas

Tropical / equatorial latitudes · northern hemisphere · 65 m elevation

The north celestial pole stands 18.2° above the horizon, so stars within 18° of it never set from here.
About 65.6% 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 42.8° up, clearing the horizon haze comfortably.
The Large Magellanic Cloud only reaches about 2.1° altitude, so it is a low, seasonal target rather than a year-round one.
At 65 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
