I have deer that regularly come into my back yard (waaaay back, unfortunately). Usually it's in the early morning or early evening. Only very occasionally in the afternoon. I'm looking for something to be able to watch them, without much fatigue. I've tried watching them with binoculars (just cheap Nikon 7x20s) and a camera with telephoto lens. Both are tiresome for any extended time and have a limited field of view. I would like to find something to be able to mount on a tripod or something, so I don't have to hold it the whole time. It would be nice to be able to keep it focused back there and be able to look occasionally. I'm thinking about a telescope or a spotting scope. Which of these would be better? Since it usually happens when it's darker, which would gather light better? (I don't really know how to tell what the magnification power of a telescope is, when it is listed as something like a "Six Inch" mirror, etc.) Would a pair of approx. 20x binoculars on a tripod work better? Also, any brand recommendations would be welcomed. Thanks!
