Granulation Cellular pattern covering the entire Sun Granules (bright isolated elements) and intergranular lanes

(dark background) Bright granules: upward-moving (blue-shift), hot parcels of gas Intergranular lanes: downward-moving (red-shift), cooler

material Intensity contrast (Planck spectrum)

Contrast in excess of 10% Seeing attenuated high-frequency part of the power spectrum

diminishing the contrast of small-scale features Solar eclipse are used to measure the telescope MTF Image restoration Power spectrum analysis
