Sun pic

Here's an unprocessed pic of the sun taken confocally. The filter was tuned to show surface detail rather than prominences. Spot 1131 is clearly visible, with 1133 above and to the right.  Note the structures around 1131.  Temp when this pic was taken was 18 degrees F--pretty darn cold, but worth it.  Much more detail was visible with the eye, including a large filament between 1131 and 1133.
