Well thought of.

I remember searching for an overhead line breakage during the blizzards
of 1981 and my colleague and I had to approach a farm. There was an
elderly lady living there (we didn't know that) and we had to tread very
softly and try to re-assure her when we knocked on her door at about
11.00 pm Fortunately there were no dogs around.

Quite right! I have recently been breeding a good collection of glow-worms.
Re your proposal on http://www.thenmc.org.uk/phpBB2/index.php for a "high

Hey! That's not my idea that's Bryn, I just posted that message into
the forum because he can't handle a web browser... bless ;-)

Anyway he's a "torchie", barking mad mind you, but still a
"torchie".... that said I can forgive him - he has a penchant for, er,
shall we say "night climbing", others might call it becoming benighted
but I choose to be charitable!

I seem to remember that as well, probably from the New Scientist.

Wanna bet? If there's enough light to see there's enough light to take
photos. Currently making plans for a series of night shots.

And even when there's not enough light to see. It's amazing what the
camera can pick up on a long exposure when the eye percieves it to be
dark.

Did some night photos while on hols, often while getting up in the
middle of the night to play the 'get the towel out by the pool' game.
(it became a game in its own right, and nothing to do with getting a
space by the pool). Once I've got through the several gig of data, I
might find out if the results were as good as the previews.

If I wasn't allowed to go walking, there was no way I was passing on the
photography!

Even easier with a digital camera. Guess the exposure, take a shot,
review the results. If the exposure is wrong adjust and take another.

At this time of year in the UK the sun rises somewhat south of east
and sets somewhat to the south of west. The moon rises and sets
opposite the position of the sun's set and rise respectively. So it is
currently rising to the north of east and setting to the north of west
much like the sun does in summer.

For your information the next Full moon is on the 26th of November

moonrise is 15:26 at 50 deg.
(sunset 15:58 at 236 deg)
moonset on the 27th at 8:36 at 313 deg
(sunrise at 7:38 at 124 deg)

What digital camera can cope with a six hour exposure though.....

The sort that astronomers use. 8>. With Peltier cooling to reduce the
noise to near zero. Of course you need a telescope and a computer to
hook them to, since they don't come with lenses, screens, or anything
like that.

You have changed the criterion from "see a single photon" to "continual
observation of an object". Obviously a single photon would appear as a
flash.

That very page though demonstrates that although the rods are
each possibly reacting with a single photon, it takes many more photons
of light (approx 12-13), because of inefficiency of the process.

"The results shown above are for transmission of 8% of light from the
flash (92% absorption)"

This is a misuse of "see". The eye photon detecting machinery can
react to a single photon. But you "see" by forming and image, and you
can't form an image with a single photon. And even though a single
photon can be detected, it doesn't bother reporting the incident back
to headquarters.

And no matter how many photons hit the retina, you never see any of
them. You don't even see the image formed on the retina. What you see
is a projection, a hypothesised "something out there" which caused the
image.

In which case how do you explain the phenomenon of the new moon?

The moon rises and sets in (nearly) the same place as the sun. They
both travel within the ecliptic, with the moon having a max deviation
from the sun's track of about 5 degrees.
