Night Vision Old German Night Vision Scope

[matman1]

I just picked up this old Zeiss/Telefuken night vision scope for 150. As it can't seem to focus. I'm going to be taking it apart and fixing it. It nothing else it should be a cool decoration. Also sorta wondering if Ii would be able to rebuild/reprint the middle part where the image intensifier is and add in a gen 3 tube and get a cheap scope.

However I'm wondering if anyone has more info on it. The seller says it's a cascaded gen 1+ tube. Does anyone have any info on them?

What's the power source?
Is that compatible with a new type tube?
Maybe 3d print a housing for a new small tube to fit in large old tube space

I may potentially separate the whole middle/rear portion of the scope from the optics up front then mill an enclosure for a gen 3 tube + battery and then put on a pvs14 ocular. This could make it into a gen 3 sight or a clip on if the reticule is attached to the gen 1 tube.

the offset optics at the rear may be a concern to re-align

the old simrads sucked

Yea I’ll have to see

Telefunken.

Just LOVE that name.

If I ever have a son, I'm naming him "Telefunken."

Yeah, but when was the last time you were actually able to see your dick?

Like I said in your other thread, I think its a Gen1 predating the Orion I used as the housing and eye piece is different. Your fuzziness is either because of the gen1 shittiness, or now that its been mentioned, the weird eye piece that they got rid of by the time they issued the Orion.

Spice it up a bit. Telefunken Des Suza Cyclops Horta. Yep, now that is catchy.

Not saying this is for sure your issue, but I've had to repair the focus mechanism on two german Zeiss Z51 Orion scopes over the last few years. Whoever "refurbed" the two that I had to do surgery on managed to masterfully butcher the placement of the internal focus gear in relation to the position of the external focus lever/knob and apparently never bothered to test it afterward. I've had eight or nein (see what I did there?) of them and all mine were fine, but two of my buddy's scopes were basically useless due to this. I can't say that I have used that specific model, but it may have some similarities internally.

ETA: Be careful if you decide to put it under the knife, gen 1 stuff stays essentially "on" for a while after you turn the power off due to capacitors slowly discharging. This adds some time to the mess with and then see how it looks cycles.

I have just received one of the Z51 Orion scopes and it does not quite focus to infinity; stars are as small donuts instead of dots, similar to mirror type telescopes out of focus. Could you provide any information, at my own risk, for adjustment? Is the infinity focus stop internal, or as simple as adjusting the external focusing knob?
