The lenses screw out, the electronics are in the body and this involves removing all the screws, including the ones behing the rubber casing. Why do you wish to strip them out?

I have a newcon-optik stargate that will only come on about 1 second after I press the lever. It only worked about a week after I bought it although I can't send it for repair under warranty right away...

Hello, it could a bad switch. Have you tryed hold down on the switch and see that works. If so, then the switch is faulty. You know that this NewCon Optik CON STARGATE-M is Russian manufactured by Optik one of the six or seven Russian companies manufacturing these NV devises. GB...stewbison

Where to access the battery compartment to replace batteries on Tasco NV 356

It could be on the top with a small hatch door that holds two AA batteries. Also, there could be a screw in cap on the back that could hold one or two CR123A 3 volt batties.

Unless it has finger crip lever on the top, this piezo electric plunger. The plunger needs to be activated about twenty plus times to build some current for the storage capacitors that will charge a small batteries. stewbison

Was wondering if there was anyway to take the lens off my Newcon BN356/BN456 Binoculars to clean them?

Yes, First, when you take the lens off you binocular make sure you are in a very clean room.
All you have to do is unscrew them. Use a good lens clean that is anti-static. If you don't every piece of lent, dusty bugs, flaky shin, etc. will be attached to those lens. stewbison

My yukon20041 infored light has stoped working could it be the bulb can it be changed etc

Yes, some time the IR illuminate is encased in a small tube. Just unscrew the cover on the IR and see if you can remove it from the. Also sometime IR illuminator is in the back with a couple screws holding it in place. I will also tell it could get to be complicated. Just take you time and you will succeed in your endeavors.

Little black and white dots inside the lens

It's not a problem with your NV monocular. These spots will occur on any image intensifier tube. EXAMPLE: Military standard states that if more than one black spot appears on the tube, then this image tube is rejected for use by the US Military Now like you NewCon Optik DN 140M it manufactured in Russia and they quality control doesn't even match the US Military Standards. On scale 1 to 10; US Military rating for the image tube would be 10+ while the Russian maybe 2+ and I said maybe. Another thing to remember here is that no two image intensifier tubes are the same. It just like finger prints on people not two are the same. It normally. stewbison

I can't figure out how to dismantle the eyepieces on a pair of 10x80 WW2 German luftwaffe binoculars to get at the lenses

there should be a beveled lock ring on the eyepiece.look at it closely...there should be numbers or letters on turn the eyepiece in half way....hold the eyepiece with one hand and wrap a piece of rubber cord around the the bottom of the eyepiece that has the numers or letters on it and twist ,,,it should come apart...the eyepice is actually two pieces the problem is sometimes you will have to apply a little heat to break the seal do not use pliers or it will damage them ..if i can talk you through it i will.. give me a call at

Tasco nv 356 night binoculars

Check the HV to the tube and see if you can see any discolouration or spots on the tube - they often indicate tube failure. Many binoculars use the one power supply for both tubes as the current demand is very low. Often, one tube operation indicates tube failure, but a wire or connection could be at fault.
