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). |
