Comet C/2025 R2 (SWAN) passes above black sand dunes in Auckland, New Zealand.
After weeks of cloudy nights, I was lucky to have one clear evening to capture the comet, while my partner climbed the dune summit.
Though too faint to see with the naked eye that night, its subtle green glow was captured here alongside the Milky Way and the soft hues of surrounding nebulae.
