Haleakala summit - as seen from sea level
As I was chasing turtles on the beach around sunset, the twilight glow on the mountain caught my eye. Situated at a little over 10,000ft, the observatory at the top is part of a global network of space lookery & mapping. There have been a number of new discoveries that were first observed from this very spot.
Shot this on a Sony a7Riii + 100-400GM, hand-held at dusk. Kinda low light, kinda long reach, but still manageable.
