This is the Fabry-Perot observatory located at the Pisgah Astronomical Research Institute, a non-profit institution located a 90 min drive away from the Clemson campus.  The FPI etalon received from the Univ. of Calgary was repaired by ICOS, an optical company located just outside of London and managed by a delightful man named Chris Pietraszewski, (Chris.Pietraszewski@icopticalsystems.com), who was able to replace the spacer posts that had been damaged in transit with a new set of posts, which was 1.0 cm in length. This instrument has been installed in the old telephone building that was no longer needed for its original purpose. The Science Director, Dr. Michael Castelez, has been very helpful with the installation of this instrument.
