The sun angle is very low in this twilight zone, so features cast long shadows in sharp relief. Now direct your binoculars to the planets. You should see four bright points of light around it. Note how their relative positions change from night to night as each moon moves around Jupiter in its own orbit. Try noting the same effect with Mercury as it moves through a similar alignment.
Some planets are squarely binocular and telescope targets.
If you're armed with a finder chart, two of them, Uranus and Neptune, are easy to spot in binoculars. Uranus might even look greenish, thanks to methane in the planet's atmosphere. Once a year, Uranus is barely bright enough to glimpse with the unaided eye . . . Distant Neptune will always look like a star, even though it has an atmosphere practically identical to Uranus. Saturn's rings are worth a look through binoculars.
