Remember we set off to take a look at the highest unclimbed mountain of the world? Turns it out we got the best look at Gangkhar Puensum (7570 m) through the giant Nikon telescope donated by the Japanese expedition that was disallowed to climb it but managed to conquer Liangkang Kangri next to it instead. The telescope is installed near the Dochu La pass at about 3000 m.
