Hi Guy's,
Whilst surfing the net for information on binoculars I came across this document.
http://www.optik-knigge.de/PDF/Fernglas-ABC.pdf
I hope thie link works and is of interest, first two pages are in German and the last 2 in English but it expalins bionocular terminology, Twilight factor, effect of coated optics etc. is a easy reading and might help when choosing your next set of bins.
Jason.
Ps Just bought a pair of 15x56 Leica Geovid's and any brighter and I'll burn my retinea's optics are superb, they've relegated by Zeiss bins to the glove box.
