    Great demo and cheers for the shout. Just wanna add a further detail: i'm only using it for sky-watching so i've covered the IR emitter with a whisky bottle cap, a snug fit precluding any leakage; the light from stars and UAP includes all wavelengths of IR, and they're obviously too far away to be illuminated by the device anyway, so emitting my own light only serves to attract bugs..
    What this has highlighted however is that the different colour modes are applied _on top_ of NV or daylight modes - so for example the green mode you get when in daylight mode is not the same image you see when selecting green mode from NV mode.
    The difference is due to the fact that selecting NV mode doesn't just turn on the IR emitter, but also disengages the IR filter that normally covers the sensor in daylight mode. This IR filter is a small thin glass pane, that slides sideways under solenoid power when NV mode is selected - and this is the mechanical "click!" you hear from all these budget NV devices when selecting NV mode. So, they're not just emitting IR light but also opening the physical IR filter shutter between the lens and sensor, allowing it to actually see into additional wavelengths normally filtered out in daylight mode (often including UV components too).
    Because the IR filter has a certain density, thickness and thus refractive index, sliding it back out of the way changes the focal length between lens and sensor, so you also need to adjust focus when switching between daylight and NV modes. Again, this is common to all similar digital NV kit.
    The take-home however is that green NV mode reveals considerably more depth to the starfield than green daylight mode, due to this opening of the IR filter shutter! In practical terms the difference between the two green modes is literally night and day, with lightyears more range.
    As a final point, this also segues into what photographers dub 'full spectrum conversion' of regular cameras and camcorders, which all rely on these same IR filters over the sensor, but which are usually fixed in place - so you can obtain similar IR sensitivity from just about _any_ camera, if you're willing to risk bricking it. This opens up the options for using things like full-frame sensors and standard lenses, along with higher framerates and whatever higher-end gubbins unlikely to appear on dedicated, much less budget, NV devices. If like me however, that's beyond your means for UAP watching.. then the NV8160 has the best sensitivity at the highest contrast ratio of any device i've tried so far.
    NB it also has consistent framerates (although you can set it to automatically trade framerate for sensitivity if preferred), and negligible latency; neither of which should be taken for granted with digital NV!

      Thanks for sharing your knowledge with us. It's a fine NV camera indeed, especially for that price.

    Hey, noob here trying to setup a similar rig, can u recommend a budget setup, all parts: telescope, ir emitter etc?

    • @starsandnightvision

      You can get the NV8160 for as low as $85 on Amazon. Zifon PTZ is around $60. No telescope or IR needed.

      Muy comparable a nivel de calidad de imagen. El NVG10 tiene mayor campo de visión y Wi-Fi pero me gusta tener el NV8160 frente de mis ojos y no tener que mirar un telefono movil. La experiencia es más imersiva y es más fácil seguir objetos en el espacio simplemente con mover la cabeza. Ademas el Wi-Fi del NVG10 no siempre es estable y se puede perder momentos importantes.

    Useless for tactical purposes. an IR emitter on your head makes you a beacon for anyone with good NV.

      That’s true and also false depending on the kind of ir emitter, there are some “4th generation emitters that do not show as much as a regular IR ammeter
