I'm looking at splashing out on some better spotlighting equipment and, as
usual, the Birding-Aus archives are providing a wealth of information. Red
seems to be the accepted filter for minimising harm to the animal's eyes,
however, I note that the Lightforce spotlight catalogue lists - in addition
to red filters for light shy animals - green filters as being "specifically
for spotting animals with sensitive eyes".

Any experts on the eyes of mammals or nocturnal birds out there? Is a red
filter better than a green one? Have any of you used a green filter?

Also, does anyone out there have advice on whether a yellow or blue filter
is more effective for spotlighting in foggy or rainy conditions?

Thanks for any info.

Carol
