A clear blue sky today with a little high turbulence. Three images are shown - first is at 540 nm showing the sunspots; the second and third images are at 656 nm (Ha) showing the chromosphere and prominences. All are single exposures with a Canon 550d camera. North is up and west to the right in all images. Thanks for viewing.
