Atmospheric refraction in the Earth's atmosphere, could be something to consider if the moon was closer to the horizon jacob, and their positions were right, but this image was taken around 00:45 in the morning so the moon and Uranus would have been about 12 degrees to the west of a line drawn north and south (meridian) so it's not likely.
No atmospheric refraction for the moon as it has no atmosphere to speak of.
