GREGOR is a solar telescope, equipped with a 1.5 m primary mirror, located at 2,390 m altitude at the Teide Observatory on Tenerife in the Canary Islands. It replaces the older Gregory Coudé Telescope and was inaugurated on May 21, 2012. First light, using a 1 metre test mirror, was on March 12, 2009.

The Bradford Robotic Telescope (BRT) is an autonomous astronomical telescope located at Teide Observatory, Tenerife in the Canary Islands. It is owned by the University of Bradford and was built between 2002 and 2004 for remote use by schools and individuals worldwide. As of November 2009, the observatory has returned over 70,000 images and has more than 23,000 users.

Teide Observatory, IAU code 954, is an astronomical observatory on Mount Teide at 2,390 metres (7,840 ft), located on Tenerife, Spain. It has been operated by the Instituto de Astrofísica de Canarias since its inauguration in 1964. It became one of the first major international observatories, attracting telescopes from different countries around the world because of the good astronomical seeing conditions. Later, the emphasis for optical telescopes shifted more towards Roque de los Muchachos Observatory on La Palma.

The Telescopio Carlos Sánchez is a 1.52 m Dall-Kirkham type infrared telescope with an equatorial mount and an f/13.8 Cassegrain focus. It is located at Observatorio del Teide on Tenerife, and is operated by the Instituto de Astrofísica de Canarias. It was built in 1971 by the United Kingdom and has been used for a wide range of infrared observational programmes, from large-scale Galactic Centre mapping to stellar oscillations.

The QUIJOTE CMB Experiment is an ongoing experiment started in November 2012, and led by Rafael Rebolo López, with the goal of characterizing the polarization of the cosmic microwave background (CMB) and other galactic and extragalactic emission in the frequency range 10 to 40 GHz, at angular scales of 1°. These measurements will complement at low frequency and correct from galactic contamination those obtained by the Planck satellite from 2009 to 2013.
