Description

A low ground fog rolls in around stargazers at Harrington Beach State Park in southeast Wisconsin on July 14, 2013. The fog came in suddenly, but was not very deep and left a clear and very steady view of the stars above, but covered telescopes in dew. Visible in this frame, which looks northeast, are the Double Cluster and the Andromeda galaxy. The photo was taken with a Nikon D700 and a 24mm f/2.8 lens set at f/4. Exposure time was 30 seconds at ISO 5000.
