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.[1]
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) In order to bring the eyepiece of this telescope to a level that does not require observers to climb a high ladder, the optics on this telescope were modified by Custer's Research Director, Jeffrey Owen Katz, Ph.D., and Research Committee Member, Justine Haupt.
The Custer Library
The Custer Library contains a wealth of Astronomy and Science books dating from the 19th century to the present. It also houses the Institute's videotape collection and 35mm astronomical slide collection. It contains National Geographic, Sky & Telescope, Astronomy, and Scientific American magazines dating back numerous decades. Membership to the Custer Institute grants access to their library.
The Custer Museum
The Custer Institute Museum (in place prior to the dome renovation but currently unavailable) contains the following in its collection:
- Henry Fitz, early Custer member and famous telescope mirror maker's Grinding Table. (Similar to the one on display at the Smithsonian in Washington, DC.)
- James Short's circa 1750 Gregorian telescope variation designed to read the separation of binary stars. One of only three known to exist.
- Various other 18th and 19th centuries vintage spectrometers and sextants, along with other astronomical devices.
- The Custer Rock Collection including geodes and numerous Fossilized Rocks.
- The Custer Meteorite Collection, which includes a Shergottite from Mars.
- Numerous astronomical, sunspot, and aurora pictures taken by past and present members.
- A broken 1750s roadside Mile Marker, recovered by Custer members that was originally ordered by Ben Franklin when he was the head of the Colonial Mail system.(Today, most of the other markers, still undamaged, mark the distance along the Main Road between Orient Point and the Old Riverhead Court House.)
- The Custer Civil War Bullet Collection.
- A piece of a tree that was originally planted at Bronx College by Albert Einstein (who often summered in Southold).
