NIGHTSKY ICE OCEAN - closer to the noctilucent clouds 4K

People and scientists have been eager to study NLC’s for a long time, without really being able to do so (or having the ressources/reasons to). That’s why they are conducting this type of program now, and that’s why they have enjoyed visionning my videos of NLC’s. As I was also trying to get ground-based footage of these intriguing clouds, I always wanted to get closer, using a longer focal length. Below 100mm, the clouds form a magnificent electric-blue glowing sheet against the night sky, which is in itself, something from another world. However, when you switch to longer focal lengths like 300mm or 500mm, you start noticing structures, shapes and behaviors that would totally go unnoticed with the naked eye.
