The IAC80 telescope, setted for observations in the optical, was fully designed and built by the Instituto de Astrofísica de Canarias (IAC) and it was the first of its class developed in Spain. In 1980 the IAC started its development and was finally installed at the OT in 1991. This telescope has an equatorial german mount, with an effective focal ratio of f/11.3, effective focal length of 9.02 m and a primary mirror of diameter 82 cm. The instrumentation is installed at its Cassegrain primary focus.
The IAC80 telescope is an ideal telescope for long-term programmes, collaborations with other telescopes, urgent observations in service or ToO observation modes, student practices and observational or instrumental test-bed. IAC80 is a key part of the Teide Observatory because of its versatility and availibity.
The current common instrument at the IAC80 telescope is CAMELOT2 (‘CAmara MEjorada LIgera del Observatorio del Teide’). CAMELOT2 is a wide field camera, with 4096×4096 pixels of 15×15 microns/pixel and 0.336 arcsec/pixel, with a 12.3 arcmin FOV due to the filter wheel vignneting (see CAMELOT2 page for more information). This detector has four readout channels and is sensitive in all the optical range. CAMELOT2 uses a close-cycle cooling system to reach -105ºC.
