About the Treworgy Planetarium

Nestled within the “formal gallery” region of the Mystic Seaport Museum is the Treworgy Planetarium. Originally named the “Seaport Planetarium”, it was re-named in 2009 in honor of Don Treworgy, its beloved director of 44 years, who had passed away earlier that year.

The Treworgy Planetarium houses a 30-foot dome with concentric seating for up to 85 people. In the center of the room, a Spitz A3P star projector displays the night sky upon the dome. Additional digital projectors are able to project square-frame (non-fulldome) slides, images, and video clips onto the dome.

Today, the Planetarium delivers 3-4 public programs every day to visitors of the Mystic Seaport Museum. In addition, we host school groups, scout troops, and local community organizations for special workshops. Advanced lectures and telescope observing occur during the summertime, and courses on celestial navigation take place in the spring and autumn.

About Mystic, Connecticut

The Mystic Seaport Museum is located in Mystic, Connecticut, a popular tourist destination situated halfway between the cities of Boston, MA and New York, NY.

The nation’s premier maritime history museum consists of three main regions: a working shipyard where we maintain and preserve a collection of historic vessels; a re-assembled 19th-century village where visitors can learn about life during a bygone age; and a series of “formal galleries” designed to further enhance the maritime experience.
