Details:
When solar activity is low and solar features are at a minimum I remind myself that the Sun is the most perfect sphere ever observed in nature. Note the approximate size for Earth in the lover right. I used my 40mm PST, a 1.5X Barlow and a DMK 41 camera to merge six images creating the total disk.
