Photo365 – Day 78 – Full moon

Had to take advantage of the supermoon tonight. Every 18 years or so the moon is closet to the earth known as its perigree. At this time it appear about 14% larger and 30 percent brighter.

I took this shot using a Pentax K10D with a Tamron 500mm mirror lens and 2x flat field converter. The combination gives an effective magnified crop equivalent to 1500mm.

The shutter speed was 1/320sec at ISO200. The Tamron mirror has a fixed aperture of f/8 and the 2x adds two stops making an equivalent of f/16.
