## Overview
McDonald Observatory is a working research observatory perched in the Davis Mountains, and its public Star Parties are the real thing — evenings under some of the darkest skies in the continental US, with research-grade telescopes pointed at the same objects the astronomers study by day.

## What to see
Planets, star clusters and deep-sky objects through the observatory's public telescopes, plus a naked-eye Milky Way overhead.

## Highlights
- Working research observatory with public evening Star Parties
- Frank N. Bash Visitor Center anchors daytime and evening programs
- Sits at high elevation in the Davis Mountains, among the darkest skies in the US

## Tips
- Reserve Star Party tickets at least three weeks ahead
- Cell service is spotty to nonexistent nearby — reliable service is generally limited to Fort Davis, Alpine and Marfa
- The observatory is open Tuesday–Saturday, 12–5 p.m. for daytime visits; evening programs are separate
