Assuming the viewer is far from any light pollution, it is a cloudless night, and humidity is very low. What is the faintest apparent magnitude of stars visible to the naked eye during a full moon (at zenith) if the viewer is looking towards the horizon?

    $\begingroup$ Shouldn't you be asking about the faintest stars that are visible, rather than the brightest? $\endgroup$ – D. Halsey Sep 26 at 0:47

  • $\begingroup$ So what you're really asking, I think, is what's the faintest visible star visible on the horizon at midnight (sun opposed) when the moon is not in the field of view. A nice clean, dry, cold atmosphere means there's almost no scatter from the moon's output into your FOV. $\endgroup$ – Carl Witthoft Sep 26 at 14:42
  • $\begingroup$ Would there be no scatter of the moon's output reaching the FOV I'm asking about? I didn't know whether there would be or not. $\endgroup$ – Bob516 Sep 26 at 16:08
