#Repost @danielkordan with @repostapp ・・・ ALMA was very strict in terms of medical examination: we needed to drive up to 5000 meters to see amazing radio telescope array. So we passed high altitude medical exam before the visit, and they checked the oxygen level all the time we climbed up to telescopes. It's really hard to breath and to move at these altitudes! You are just getting out of breath in a few seconds under the strong wind! So we picked up portable oxygen balloons with us, which helped a lot! We could move fast and stars seemed to be brighter while you breath oxygen. That's a lot of work in this big panorama of telescope array: DanielKordan.com 5 vertical shots panorama, shot with l plate and nodal rail, Aperture f/2.8 Shutter speed 30 s ISO: 4000 Nikon D810A AF-S NIKKOR 14-24mm f/2.8G ED #Chile #alma #special_shots #radio #natgeospace #nightsky #night #nighttime #discoversouthamerica #astrophotography #apod #stargazing #longexpoelite #universetoday #travel #earthpix #awesome_earthpix #discoverearth #awesomeearth #thebest_capture #wonderful_places #travel_captures #instagood #instacool #amazing_longexpo #longexpoelite #SpaceAttraction #nightphotography (en Proyecto ALMA, San Pedro de Atacama.)
