yes - great link. This was what I referred to when describing the DIY project with the three stage cascade tube (p8079hp) in the post on Generations. These can be made for relatively low cost and work. They are just heavy and bulky, but the performance is pretty good and clear view in the center of the fileld with some distortion around the edges easily enough ignored. Nice find on the actual instructions. Thanks.
Cheers von..been digging around after reading your great posts.the route I will be going down .I cant afford the all singing and dancing kit ..so diy dave will start his bodgering.lol. already got a plan In the head. going widefield. .. hope to rig a slr lens to an intensifier tube and rig it to a watec 902h video camera. Going to adapt my multi camera array to take this set up when i find a nice cheap gen3 on ebay..i wont jump in till im right up to speed on image intensifiers. So my multi camera array will be a selection of kit . ed80 with a sammy scb2000 or 2001. Phil dyer camera with 20 sec intregration on a wider lens..my qhy5l ii on a orion mini finder guide scope and the abive when complete. Analogue av cam feeds to my toolbox control set up, cctv dvr ,4 channel 1.5 tb hard drive.to 15" monitor built in to lid ..all powered frim 12v dc 22amp golf cart battery.

Those tubes have tremendous gain too. They make a kind of high pitched whine when powered on, but its three tubes all in one and powerful. If you setup the camera part right, you might just have a small enough image circle with it to just capture clearest part and not even see the edge aberrations. Should be a worthwhile project. It will blast narrowband too with a sensor on it and some integration time plus a little noise reduction by stacking or whatever means the camera has. Whenever you get around to it, I'll be interested to see results.
