Sun spots in a hot afternoon

This photo has been taken at 820mm focal length using a Nikon d3100 DSLR camera. A Baader astrosolar foil has been used. This cropped image almost expresses the visual experience through the scope. It captured in Nikon's NEF (RAW) format to prevent data loss, a well known problem of JPEG files. The software Aperture v3.1 (Mac) has been used for further processing.
