Kazoo beat me to the ATN X-sight II recommendation, they come in 3-14x or 5-20x...
The zoom is digital, so you lose resolution as you zoom. They also work as a day scope, just not without power... they are an HD camera and a little screen, no glass straight through. They also go thru batteries quick.
There are other features, like they can capture video on an SD card... I'm planning to get one for hog hunting, but don't have one yet.
