Diurnal studies do not predict nocturnal habitat choice and selection of european golden plover and northern lapwings. Gillings et al.

It was a 300mm camera lens not 400mm as I first said, so magnification would be 6x plus what ever the image intensifier was (maybe 2x) giving around 12x mag overall. To me this seems feasable, I presume they used the the camera lens in a similar manner to a digiscoping setup (I presume you might not be familiar with the digiscoping concept?). Basically the camera lens acts as a light gathering source, this is much more than an objective on a normal night vision scope. The 100mm canon 300mm f2.8 lens has a 100mm objective lens capable of gathering a huge amount of light c. 4x that of a 42mm objective lens. The image intensifer then sits behind the camera lens. Anyway I will have a go and let you know.
