A good
star map that goes down to magnitude 7.0 or so is a basic tool for learning celestial navigation, but a
binocular can also be quite useful for learning this essential skill. The view through a
binocular, like the view through a typical finder scope on a telescope, can be fairly close to what you see on a good star map, though much depends on your observing site. Here in my light polluted area, my Pocket Sky Atlas is a pretty good match for my
Nikon 7x50 Prostar binocular. Not that I planned it that way, but who's complaining?
