Would you mind explaining that in the common vernacular?
Sure! The pupils in our eyes are what let light hit our retinas. Our pupils open to a maximum of 7mm when we are young ( when we get older, they don’t open quite as much. The picture from APOD was taken with a 6” diameter lens- think of a 6” diameter pupil. The light gathered by that lens is much, much greater than what our eyes actually see, consequently, we can then see, thru a telescope, celestial objects that are invisible to our naked eyes. Not only that, but the camera used by the photographer has the ability to keep gathering light on its sensor, collecting more and more photons of light until the invisible becomes visible and the photographer processes the image in a computer.
