Absolutely calibrated measurements of the reflectivity of Saturn in 1992 are presented. The observations were carried out using a Circular Variable Filter in combination with a photometer with a single element InSb detector at the 1.54m Carlos Sanchez infrared telescope of the Observatorio del Teide in the Canary Islands (Spain). The spectral

The Instituto de Astrofisica de Canarias (IAC) has presented the proposal for the Observatorio Roque de los Muchachos (ORM) 8 m telescope. As a part of this project, we have proposed a distributed control system using the Controller Area Network (CAN) protocol for the control of hundreds of force actuators for the support of the 8 m diameter thin

The Instituto de Astrofisica de Canarias (IAC) is taking preliminary steps towards the building of an 8-m class optical-infrared telescope to be placed at the Observatorio del Roque de Los Muchachos (ORM) on the island of La Palma in the Canary Islands, Spain. This paper presents a brief description of the preliminary conceptual design of the

We have just finished the first tests at the telescope of an infrared camera designed and developed at the Instituto de Astrofisica de Canarias (IAC). This camera, based on a 256 X 256 focal plane array, has been built to operate at the 1.5 m Carlos Sanchez IR telescope (CST) in the Observatorio del Teide (Canary Islands, Spain). In this paper we
