The reason it's hard to look at the sun is it's brighter than the moon. 
Nonetheless with the right filter you can clearly see the sun's disk, which 
means the disk itself is significantly brighter than light scattered by the 
atmosphere. So I'll use an area light for the disc, and the radiosity from 
my HDR dome will handle the light from the sky.
