0.35-meter

Las Cumbres Observatory has developed a set of identical 0.35-meter (diameter) telescopes at its Santa Barbara headquarters. These are Planewave Delta Rho 350 telescopes with custom equatorial mounts and high-quality CMOS cameras. Twelve of these telescopes have been deployed to LCO observatory nodes: two to Siding Spring Observatory in Australia, one to Sutherland Observatory in South Africa, two to Teide Observatory on Tenerife, three to McDonald Observatory in Texas, two to Haleakala Observatory in Hawaii, and two to Cerro Tololo Observatory in Chile. These telescopes constitute our primary education network and are also utilized for science observations.

Originally these installations were Meade telescopes with CCD cameras. The replacement was completed in 2024 thanks to a grant from the Gordon and Betty Moore Foundation.
