A magnitude difference of 1 represents a brightness difference of x2.512, so a magnitude -1 star is x2.512 brighter than a magnitude 0 star.
“Astronomy 2006” shows the full Moon as magnitude -12.74, with Uranus a pale +5.52, a difference of 18.26 magnitudes.
Therefore, the brightness difference between the full Moon and Uranus is 2.512 to the power 18.26 which is a whopping 20,153,873!
Am I doing the calculation correctly?
Thanks

you lost me after a "huge disparity of brightness" then things went all hazy
