home made image intensifiers

Hi, I recently been looking ito a image intensifier made by Andy & Darion from Roslinton Astronomy in England. They are using a Gen.1 EEV P8079HP intensifier tub. Has anyone here made one or has used one. They can be made for $130. Very tempting. I hope somebody knows just how good they are.

Generation 1 image intensifiers display about every optical abberation known to man because of the nature of the photo multiplier. They require lenses faster than f 1.5 usually, more abberations. They can be a fun toy but not up to the task of stargazing.
