Brian;
I will certainly give your listing a try. I have no doubt that having =
the
Pole stars only up 35 to 45 degrees is limiting the magnitude that I =
could
see.
By "10 percent detectability" do you mean that you keep staring at the =
same
spot in the sky and these stars are seen for 10 percent of the =
time...or,
that you look away and then look back and 1 out 10 attempts is =
successful?
Because I drew to Little Dipper so that I could refer to it later, I am
certain that turning on and turning off the dim red flashlight effected =
the
results. That could also be an interesting addition to the trial, once =
you
have established the faintest star held steady, then take some notes and =
see
if it is still visible and how long it takes to return after the light =
is
off.
Fun, fun, fun (quoting Brian Wilson)

By this I meant that I do not "hold steady" a star this faint,
but it is in the 10-20 percent detectability range. The limit where
you simply look up and can instantly catch something is more like
the mag 6.5 that Steve quoted. But this of course is way brighter
than the real threshold for any given site.
