A Google Earth image of the Roque de los Muchachos Observatory on La Palma, showing the layout of the two LPQI-Pathfinder optical telescopes. The orange line indicates the 550-metre distance between the Telescopio Nazionale Galileo (TNG) and the Nordic Optical Telescope (NOT), which are connected via the fibre-optic network of the Canary Islands Institute of Astrophysics and RedIRIS. The dotted lines indicate the distances to other telescopes which, in future phases, could eventually be added to the project.
