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.

Radiant in Orion. Visible from both hemispheres. The Moon is 72% lit on peak night, so lunar interference is moderate.
- 2026-10-26 — Full Moon
A 100%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
- 2026-11-05 — Taurids peak — up to 5/hour
Radiant in Taurus. Favours the Northern Hemisphere, which includes Altar, Sonora, Mexico. The Moon is 18% lit on peak night, so lunar interference is low.
- 2026-11-09 — Darkest night of the coming month
The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Altar, Sonora, Mexico.

- What is the stargazing light pollution level in Altar, Sonora, Mexico?
- Altar, Sonora, Mexico is a small town — typically Bortle class 1–4 (rural to excellent dark sky), where the Milky Way is usually visible on clear, moonless nights away from local lighting. These are typical ranges for this population size, not a measured reading for this exact spot — use tonight's Moon phase and the best-nights list above to time a visit away from direct lighting.
- Does Altar, Sonora, Mexico's elevation help stargazing?
- At 414 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Kitt Peak National Observatory sits about 140 km from Altar, Sonora, Mexico at 2096 m.
- What should I plan for observing near Altar, Sonora, Mexico?
- High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 30.3° here. Cold and thinner air are the practical constraints, not the sky.
- How dark does it actually get in Altar, Sonora, Mexico tonight?
