For this composite image the polariser was aligned along the bow for the centre of each frame.
When they are combined as a panorama the result shows more contrast than the view without polariser.
Although this is a little stronger than it appeared to the eye it still does not compare with seeing the real thing.
The visual impression of a large luminous bow floating in the mist is hard to capture in an image.
