Aphid SEM

An aphid, view at 100 times magnification in a really really old SEM that uses BNC video to connect to a computer for slow-scanning image capture (it scans like a CRT - I know the film capture just eposes film to a CRT, i'm not sure if the computer electronically converts the incoming video signal or just has a CCD pointed at a high quality CRT in a box somewhere).
