**Abstract** With the advent of modern CCD cameras, it
is possible to quantitate the total photon count of distant Luminous Objects.
In this paper, I have developed a formula for astronomers to allow use of this
fact to calculate the total photon output, and thus total energy output, of
imaged objects. I then use SN 2002ap in M74 (NGC 628) as an example and
calculate the total energy flux of that event.
