Re: Best spotting scope for $500-$700
Nikon ED50 if you want something light and compact. I bought a refurb for $400 with a fixed 16x digiscope eyepiece, then added a 13-30x zoom for another $50. For $450 I'm really happy with the performance for such a compact scope.
Leupold has a similar compact scope but I don't think the image is as good as the ED50.
