Photos (June 2019) taken at Tenerife, exactly in the place next to “God’s finger”. A great place for astrophotography during night and long conversations about the nature of time, speed of light, wondering if life exists in other planetary systems…
Equipment: Canon EOS 6D (no mod) with a Canon EF 200 [mm] 2.8L II USM lens, on a glued iOptron CEM 25 mount, which I accidentally earlier crashed on beton.
