The images were taken from Kelling
Heath during the Spring Equinox star party. The sky was dark and transparent for
the first 3 luminance sub exposures, cloud then interfered. The remaining
exposures were taken on the following night which was misty and hazy. This
was the only image I secured during my cold and snowy 4 night stay at the star party.
