]] Custer Observatory is an astronomical observatory owned and operated by Custer Institute. Located in Southold, New York (USA), facing Peconic Bay and Shelter Island, Custer's location boasts some of the darkest skies on Long Island. Long Island's oldest public observatory, Custer Institute was founded in 1927 by Charles Wesley Elmer (co-founder of the Perkin-Elmer Optical Company), along with a group of fellow amateur-astronomers. The name was adopted to honor the hospitality of Mrs. Elmer, the Grand Niece of General George Armstrong Custer. In 1942, the Custer Institute was incorporated as a non-profit educational corporation in the State of New York. In 1938, the group purchased the land the institute presently occupies and initial construction was completed in the spring of 1939. The 100-seat lecture hall was added in 1945. In 1947, through donations by Charles Elmer and Mr. Polk, the 3-story tower/library and observatory dome were built. In 1954, Charles Elmer died; that same year, the Institute added the shed, which houses three sliding roof observatories. Over the years, Custer has acquired a large collection of telescopes of all sizes and descriptions. Most recently, this includes a 25-inch (f/5) Newtonian reflector, which is now the premier telescope in the newly-rebuilt dome. (Article not found) This telescope will soon come to represent a one-of-a-kind optical system; the result of the latest optics research and innovation conducted at the Custer Institute.

Very friendly staff. All sorts of people come to share their interest and watch the skies on good Saturday Nights. Yes it's far out east but the staff and patrons are so polite well classed people, don't worry about not fitting in with the demographic the staff here don't care about how you look or where you come from, all they care about what you're here to see (the stars_ and are happy to show and explain and share the night :) Just bring a buck or two to donate as Custer is a non-profit and operates on its members interest in stargazing viewing to the public is free on Saturday nights, it relies on the goodwill of the patrons to continue this great service

A wonderful place for all. Telescopes are open to the public EVERY Saturday night (weather permitting). The big Dobson scope in the dome is AWESOME, and they have the darkest skies on long island. Enthusiastic astronomers explain everything, and make the heavens come alive! It's only about 45 minutes beyond Riverhead, and there's lots to do on the way (such as winery tours, farmstands, fine dining, and nice scenery).
