A few thoughts on night vision:

Quite a lot of documentaties are filmed, as far as I know, with normal,
white light. Although a lot of animals only come out when the sun is
down, they don't seem to have the brains to avoid, or even register,
actual light. Knowing that, you can see an amazing lot of wildlife with
a flashlight.

In my parents home, we used to have a handful of birds (mostly
parakietes) zooming freely through the house. The way to catch them (if
we ever had the need) was to turn of the lights and catch them by
candlelight. I don't know if the birds can't see that specific
wavelength, or the light was just too dim for them, but fact is they are
completely blind in that light.

Hunters and fisherman sometimes (illegally) use a bright source of light
to attract wildlife. Bringing light might be a way to see more wildlife
then you ever imagined possible. However, you will be upsetting their
normal routine with your light. I wouldn't want that.

Anyway, I think there is a lot to explore before buying incredible
expensive electronics.

Niels.
