Cheap intensifiers for popular all sky cameras?

See Subject. Anyone know whether such intensifiers might be available
say for some Watec or similar cameras?

Intensifiers are not camera specific. Besides the intensifier, you'll
need two lenses- one that images the sky onto the intensifier
photocathode, and one that focuses the intensifier screen onto the
camera sensor.

There are cheap first generation intensifiers available (Russian
nightscopes and surplus), but they have a lot of distortion and poor
S/N. For good results you usually want a 2nd or 3rd generation
intensifier, and they are generally fairly expensive (hundreds of
dollars or more).

Most amateurs get them on eBay.
