Mt. Wilson Meets the Lyot Double Image Micrometer
Abstract
As part of the Mt. Wilson Double Star Workshop, the authors used a double image micrometer to observe two double stars, STF2383CD and STF2583AB, on the night of July 19, 2013 (B2013.547). The instrument was designed in 1949 by Bernard Lyot and built by Meca-Precis. We found separations of 2.53±0.29'' for STF2383CD and 1.58±0.40'' for STF2583AB, and positions angles of 77.8±2.3° for STF 2383CD and 103.4±1.6° for STF2583AB. The scarcity of double image micrometers and the opportunity to use the historic 60 inch telescope at Mt Wilson made this workshop a very unique experience.
