The Carlos Sánchez and IAC80 telescopes, known as TTNN and located in the Teide Observatory, are telescopes manually operated by astronomers (in person or remotely) through specific computer applications developed mostly in the 90's. These applications allow the control of the movement of the telescope (motors and encoders), as well as the

FRIDA is an Integral Field Unit (IFU) based on an image dissector system using mirrors, and several optical cameras to cover different spatial scales sampling the GTC diffraction limit in the range 0.9 μm - 2.5 μm. Unlike all instruments installed or planned for GTC, FRIDA is the only one that will work with extreme spatial resolution, a factor 10

EDiFiSE - Equalized and Diffraction-limited field spectrograph experiment - is an instrument developed by IAC for tehcnological demonstration. It includes one Adaptive Optics system and one Equalized Integral Field Unit Spectrograph.
