Image intensifiers are really awesome. Microchannel plate CRTs use the same technology and allowed capturing single high speed events on film before digital oscilloscopes.

They are difficult to beat with modern technology (CMOS sensor) because they are much lower power than equivalent digital system, and have no latency. Think night vision goggles using 9V alkaline battery..

Telescope cameras typically only use CMOS sensors, why aren't image intensifiers used there?

Image intensifier is better for real time video, but is noisy compared with still images taken with long exposure cooled CMOS sensors.
