The Bernard Lyot Telescope (Téléscope Bernard Lyot, or TBL) is a 2-meter Cassegrain telescope operating in the visible domain since 1980. It is located at an elevation of 2,877 meters on the Pic du Midi in the French Pyrenees. Since 2007, the Bernard Lyot Telescope has housed an echelle spectropolarimeter, NARVAL, which allows astronomers to probe stellar magnetic fields with exquisite sensitivity.
