Abstract:

For the past twenty years, the primary double star observational technique utilized at the US Naval Observatory USNO has been speckle interferometry. Our two speckle cameras have been used on a variety of telescopes our 26-inch in Washington, the Naval Observatory Flagstaff Station NOFS 61-inch the McDonald Observatory 82-inch, the Mt. Wilson Observatory 100-inch and the twin 4 meter telescopes of Kitt Peak National Observatory KPNO and Cerro Tololo Interamerican Observatory CTIO. While these instruments have each yielded many observations, they have been involved in rather different programs, with the 26-inch observing primarily the so-called neglected pairs and larger instruments conducting duplicity surveys and observing close, astrophysically interesting systems.
