Hello, All,

I am looking for any information on a couple of Night Vision Devices, The First one up is a "Night Optics USA, D300-3B" monocular.
It appears to need some work as it is missing an objective lens, other than that, it appears bright with only a couple of spots..


The reason I ask is that I have a chance to buy it but with the current designation "Night Optics USA- D-300-3B" . I am not certain
if it is too big of a gamble..What would the designation of the numbers of this particular monocular lead you to believe?

The biggest question is, I am not sure if it is a Gen3 or a Gen2 device, and where can I get it repaired, if it is broken?? and
where can I get the missing parts..


There isn't a ton of information online about these, actually NONE for the "B" designation, but Ive looked at some of the D-300 Monoculars and the designation of a "3" anywhere behind the D300 on all of the devices I have seen are Gen 3 devices..

Would you think it to be a generation 3 intensifier with a grade "B" tube or something? Maybe a run of defects?




The above image shows where I need an objective lens..Can anyone point me in the right direction?



The tube appears very bright with only a couple of Black Spots but I don't know if it is a Gen 3 or Gen 2..


It needs an Objective lens that cost between 90.00 and 150.00 as far as I can tell..

Whatever it turns out to be, Gen2 or Gen3..I think I am going to rebuild it unless it is NOT worth the gamble..


A;so, Any info on a video camera night vision device known only as "Astro Scope"



Should I be able to see "Green" through it if it isn't hooked to a battery

My big question is if I can change out the intensifier tubes in case of wanting, later on, to upgrade eventually?..

I can't find ANYTHING on this one, as far as how to take it apart or tell if it is all there...

I have no way to manually inspect it because as most of us do, we deal online, SO, any and all help would be welcome..
