Local sky character in Letterkenny
Northern mid-latitudes · northern hemisphere · 8 m elevation

- About 90.9% 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 6° up, staying low, so a clear southern horizon matters.
- At 8 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Letterkenny is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.
