We have designed, built and are deploying complete 1-meter autonomous telescopes, operating as a global network with centralized scheduling. The 1-meter prototype in Santa Barbara  was used as a test facility to validate all optical, mechanical, electrical and software functions prior to wider deployment.

The first 1-meter deployment was to ELP, MacDonald Observatory, in April 2012. From there more telescopes were added to multiple sites across the globe. Read more about the deployment history of our 1m telescopes >

Currently we have thirteen 1m telescopes online, with a further two be added to Ali Observatory in China, which is currently under construction. See camera for live views of our working sites.

Telescope Structure

Mounting Equatorial C-ring
Basic Optics Ritchey-Chretien Cassegrain
Maximum slewing speed 6 degrees per s
Tracking accuracy without guiding 0.5" RMS
Blind pointing accuracy between 3 to 10 arcsec depending on cassegrain axis position
Altitude limit 15 degrees (airmass ~3.9)
Hour angle limits -4.6 to +4.6 hours


All of the 1 m telescopes (except the Wise Observatory) have Sinistro imaging cameras. Four of the 1 m sites (CTIO, SAAO, McDonald Observatory, and Wise Observatory) also have high resolution NRES spectrographs.
