Equinox Interscience (old)

Superb custom built OTAs and mounts now available from this prestigious specialist manufacturer.

Equinox Interscience originally started business in 1984 as a sole proprietorship under the name Equinox Industries and was operated by Mr. Russell Mellon to perform optical design and analysis consulting and small scale optical instrument fabrication support. Notable projects from this early period include a doppler LIDAR wind field measurement instrument built for MontEdison Spa of Turin Italy and a Tactical Airborne Laser Communications test brassboard built for the US Air Force at Wright-Patterson AFB, Ohio.

EI's expertise extends from large aperture professional observatory installations, educational facilities and advanced amateur equipment.
