About the largest extent of a rainbow you could see from the earth. This shows about 200 degrees. I have fantasized about capturing the full circle from the air but lack the means to pull it off at the moment.

The issue is related to argumentum ad verecundiam: an argument based on appeal to false or fraudulent authority. Famous example: it has been argued that megadoses of Vitamin C must be beneficial because they were recommended by Linus Pauling, a Nobel Laureate. But he was an inorganic chemist, not a nutritionist; and his prize had nothing to do with Vitamin C.
