Yup. I carry my tiny light Nikon ED50 everywhere now and it plus my EL42s are plenty for anything away from the truck for me. I use both on the super light KDC Tripod.Possible, but using your rifle scope as a spotter can be problematic for some, as it can violate one of the basic tenets of firearm safety... don't point a weapon at anything you don't intend to shoot...
You might be surprised at how versatile a system you can run with something light like bushnell legend hd 10x25 binos (8oz) and a Kowa tsn 501 20-40x spotter (14oz). Between the two, you have 22oz of glass, which is less weight than many 10x42 binos.
