I'm used to seeing zodiacal light as a point-upwards narrow cone, but is the blunt-point-downwards cone of orange light here zodiacal? And are the horizontal bars of light sticking out of the right-hand side significant? They show up brighter in a slightly later shot.
I got a sequence of this brilliant sunset over the island, each with a separate point of interest.
