Pelegrina galathea. Epigynum.

Five exposures with Canon 30D, Canon MPE-65mm and Sigma 2X teleconver, at f/4 (actually f/8), stacked in Helicon Focus Pro, with further processing in Photoshop for contrast enhancement, color correction, cropping and probably some minor dust spot removal in the outlying areas.

This image has not been resized or sharpened, and thus shows actual pixels.
