The sun was certainly low in the sky today, and in the crisp air and deep blue sky looked very picturesque. However looking in the wavelength of hydrogen light details on the sun just pop into view that can't be seen in normal light. This shot was taken with the Coronado DS40 at f10 with a DMK31 camera. It's easy to see all the activity is focused in the suns southern hemisphere corresponding to the this dual hemispherical peaking we seem to be having this solar maximum.
