You should try to put some sort of zoom lens in front of the scope and see what happens. I took an old scope today, held it in front of my video camera, which allowed me to zoom in on objects. The obvious advantage by doing something like that, compared to using the ATN's digital zoom, is using optical zoom versus digital. The image quality should be way better doing it this way.

Just a thought. 

Thanks,

Well, it's all a bit theoretical at this point isn't it KMD?

I entirely agree that Optical Magnification is to be preferred to Digital ('zoom') but I don't think the front 'Objective' of the X-Sight lends itself to this solution,

Some of the Yukon/Pulsar NV digiscopes DO have "front lenses" which can be swapped-out for camera lenses (usefully, these are usually from older SLR cameras and can be bought secondhand quite cheaply).

And one doesn't have to go mad - cheap, basic lenses are usually best for NV work (lack of IR filtering / coatings is one reason).

Seem to remember "C Mount" as being the basic required mounting system.

Yes and no. I tried it with a camcorder, and considering that the ATN X-Sight is more a camcorder, than a scope, I don't see why it [putting some sort of optical magnification in front of it] wouldn't work with the ATN as well...?!

Not sure what you mean by "lends itself to this solution"?

Good to know. I had no idea. Thanks for the input. 

That said. Someone should just try it. It cannot be that hard to take a "regular" scope and hold it in front of the ATN and see what happens. Right?

Thanks,

I've made a lot of posts on the ATN site, but I've sort of stayed away form the "add on magnification" issue. Here's why.

The resolution of the imager is indeed HD1920x1080. The viewing screen is just 1280x720. So when you zoom in, no matter who you do it, the resolution remains the same. At a high enough power, the pixilation gets severe with obvious results. If you play around with the video recording at various magnifications, you'll soon discover the limitations of the imager. It is particularly evident at night, when the scan rate reduces (CCDs require time to charge up). 

I also have a Viper. It is a scope add-on, and although the specs as decent, it isn't any better resolution wise, but the IR source is MUCH brighter. But if you mount one on a variable scope, you'll soon see the same pixelation, only a bit worse. 

Both scope EAT batteries, and an external battery pack is essential. And they're both REALLY heavy adding about 3 pounds, with the Viper a bit less than the ATN X-Sight. 

For what they are intended for, and what they're trying to be at their price points, one can't complain too loudly.

Alan, thanks for the input, even though I have to read it a few more times to full understand it. : )

Here is what I do not get: Every camera has a sensor (other than 35 mm and such), and they all have a lens. The bigger (focal length) the lens is, the more you can zoom in without losing image quality. This, of course, also depends on the quality of the glass. You can get a 600 mm lens for under $1000 bucks and one for over $30,000. They will not be the same. This goes without saying. Anyhow. 

From my understanding, you should be able to take a variable zoom lens and just "hold" it in front of the ATN, or anything else for that matter, and use it to zoom in, without losing image quality... However, I am not an expert so maybe someone else can chime in.

Thanks,

Kmd
