Neptune is just slightly below the dimmest naked eye objects from a dark sky site. Most humans can see down to about magnitude 6.5; at the moment, Neptune glows at magnitude 7.6. That puts it easily within the visibility of most any 7x35, 8x40, 7x50 or 10x50 binoculars from just about anywhere. The key simply knowing where to look.
Five steps might make this star hop sound more difficult than it really is, but because I'd like everyone to be able to see the furthest planet, I am showing this one small step at a time, so no one misses where to go. The first thing to do is get oriented in the sky. The ecliptic - the imaginary line in the sky that the Sun passes through as Earth revolves around it - is close the area where all the planets appear in the sky. And Neptune is currently visible within the boundaries of the constellation Aquarius. To get an idea of where to look in the sky, check out the Aug 25 thru Aug 31 Eyes on the Sky weekly video:
Later in summer and through fall, Aquarius may appear...
