Eclipse 2019

Complete guide to stargazing in Chile’s ‘eclipse valley’

A stargazing mecca awaits eclipse-chasers in this low humidity wonderland

A total solar eclipse will occur in Chile’s Elqui Valley on July 2, 2019. So let’s go stargazing!

There’s a ‘dark secret’ about eclipse-chasing and stargazing that you should know. Moonlight can ruin an otherwise well-planned trip to dark sky destinations, but you don’t ever have to worry about that when scouting for locations to watch any kind of solar eclipse. Why not? It’s the best time possible for stargazing by its mechanical definition; it’s only when a New Moon crosses the ecliptic that a solar eclipse can occur, so you can be assured of dark skies for a week or so before and after the celestial spectacle.

And even if you’re not into stargazing and astronomy, it’s worth going to this region just for the wine.”

Get high up into the Elqui Valley and the stars don’t twinkle, they glow. This is a haven for stargazers. Plus you can easily find a local observatory that holds public stargazing, and observing sessions through telescopes, or a resort or guesthouse that has a telescope available for guests. Such are the wonders of the southern night sky that places like these are more common than you might think – especially in Chile.

Travel to Chile for a Total Solar Eclipse with!

There are few better places in the world than the Elqui Valley for astronomy; its clear skies and low humidity make it spot-on for stargazing. “The night skies here are incredibly clear here, so as soon as you get out of the small villages the skies are amazing, and there are a lot of observatories you can visit and even stay at,” says Dan Clarke at RealWorld Holidays. “And even if you’re not into stargazing and astronomy, it’s worth going to this region just for the wine.” That’s two great reasons to visit in July 2019.

Before you start drinking, it’s very tempting to visit a professional observatory; all host regular observing sessions and the chance to look at some of the gems of the Southern Hemisphere night sky using telescopes. It’s worth finding out if any of them will be staging special events for the Total Solar Eclipse – inevitably, they will be, though most are very small, so booking ahead will likely be essential.
