This photograph is a composition of three exposures taken Wednesday morning, cropped from original size. Click image for larger picture (1024 x 1282, 600kb).
Clouds, dew and the end of darkness prevented more exposure time. I also had a few problems and inadvertantly ended up with these exposures shot at f5.6. rather than the f2.8 I intended.
