Local sky character in Calgary

Northern mid-latitudes · northern hemisphere · 1048 m elevation

The north celestial pole stands 51° above the horizon, so stars within 51° of it never set from here.
About 88.9% 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 10° up, staying low, so a clear southern horizon matters.
At 1048 m elevation, roughly 12% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
