Love your product also love how it comes in a pelican case. Shipping was fast. Please in the future sell accessories for mounting to helmets.

Have not talked to anyone yet, we will see how long it takes to get here and if everything is included that is suppose to be. Tim

Ordered same day and was shipped the same day. I Can't wait to try it out once it gets here.

Quick delivery on these sturdy mounts!

Amazing. I have a 1st gen Russian night vision monocular (about 25 years old) and might as well throw it away. The Aurora is really neat.

This is one of the best products I’ve ever bought. I can completely see everything very clear in the night. If you’re contimplating on buying one let me tell you to just go ahead and buy it. You won’t regret it.

Very enjoyable. Of course no one expects it to be as good as Gen3 NV (yet), but it really is very delightful! I have two minor complaints and a couple ideas for the "next version." First, 1)There is no way to connect a lanyard/camera strap that I can see. I don't want to drop an expensive camera on the ground. 2)There is no protective guard around the front end. A simple half-inch extension could solve that. Both of these things would easily be solved. As a stop-gap measure, I put a wrist band around the front to protect it. On the next "version 2.0" or whatever, there are a couple of things that can be done to increase the light-gain (how much brighter it makes the image over the human eye). 1) First, it has a 25mm sensor, but only a 16mm lens opening; that must be to increase resolution because of the large pixel size. if the opening entrance pupil were wider, to take full advantage of the sensor, it would be 2.4x brighter (25mm^2/16mm^2). 2)Second, in the future, both a wider objective lens and wider sensor would boost its gain still further. I am thinking of something like a 60mm opening. If we kept the same resolution, but increased pixel size 2x for a 50mm sensor, AND took advantage of a wider aperture, we could increase the light gain by around 4x, i.e., making the image 4x brighter than the current version for better images in low-light environments. 3) Astronomers are used to taking "long-exposure" photographs, where the shutter of a camera is kept open and the telescope slowly gathers more and more light, getting a brighter image than can be seen with the naked eye. If the device is stabilized on a mount, it could take a 30 second exposure and get a bright image of the Milky Way Galaxy or something else. At present it is only able to take a 1.5 second maximum exposure. Once again, this could easily be solved. This would be the visual equivalent of a long-exposure photo. As you watched, the image would grow brighter and brighter as more light was gathered. This technology could easily be turned into a fun telescope eyepiece that would increase the light-gain of a telescope beyond its limiting aperture. Visual astronomers would LOVE such a device if the view were modified to be circular instead of rectangular. They want to view something that resembles the view through an eyepiece instead of a movie screen from the back of the movie theater. 4)The other advantage that astro-photographers have over visual astronomers is they can use cameras that have wider exit pupils than the human dark-adapted pupil of 7mm. Well, this device does the same thing, but VISUALLY. It has an effective exit pupil the size of the 16mm front opening, much wider than the human pupil. That could be increased to the size of the sensor. At 1x magnification, the exit pupil will be the same as the objective lens. Overall, a great device which everyone will get a kick out of. The light gain seems to come from the following factors: 1)very large sensor 2)very large pixel size to collect more light. 3)Sensitivity to infrared in addition to visible light. 4)Slight demagnification to spread the available light over a smaller view. 5) High ISO gain factor. 6)Last, but not least, the sensors themselves capture more light than a normal sensor. This is the “black silicon” they talk about. It captures more of the available light, according to their reports. My thoughts for “Version 2.0 summarized: Larger opening aperture; larger sensor with same resolution but larger pixels; small protective rim around the front to protect the opening; ability to take long-exposure shots or the equivalent, an even slower frame rate, such as 4fps, 1fps or even 1/30 fps. For astronomical use, where the motion is imperceptible over such short periods, this would be wonderful. I am going to have a lot of fun with this and wait for the next generation version.

quick and easy!
