Enjoy,

These images were taken in Istanbul with a Nikon D 70 high definition camera and show the subtle penumbra which has been measured at 1.31 and 1.314 degrees using Digimizer. The Moon was calibrated at 0.2787 degrees semi-diameter.
The yellow grey scale wand was set at 2 pixels wide and a mean position was chosen for the second penumbra measurement.
