   How many telescopes can be used in a VLTI?

   • Although the four 8.2-metre Unit Telescopes can be combined in the VLTI, they are mostly used for individual observations and are only available for interferometric observations for a limited number of nights every year. But four smaller, dedicated 1.8-metre Auxiliary Telescopes (ATs) are available to allow the VLTI to operate every night.
