You have decided to use a CCD camera to check if a 16th magnitude quasar is variable.
With your telescope/camera combination, you know that a star with a magnitude of 0 would deliver 1 × 109 photons/second to one pixel, so this allows you to work out the photons/second from the quasar delivered to one pixel.
SO- taking out the numbers i need: My quasar is the 16th magnitude.
The star im comparing it to has a magnitude of 0.
The 0 mag star gives out 1*10^9 photons/second (1 pixel)
The Attempt at a Solution
Im not sure if "flux" and "photons/second" are the same thing, BUT if they are, then:
**Im not looking for the answer because I really want to figure this out, I just need to know if im going in the right direction, thank you in advance !! (:
