You need a telescope if you want to view Saturn’s rings. A pair of binoculars can detect the disc of the planet, but the rings will not be visible. If you have a small telescope, the rings can be seen to be sticking out from the disc.
Views of Saturn with different instruments
TOP BINOCULAR VIEW
MIDDLE 4” REFLECTOR
BOTTOM 15” REFLECTOR
The top image is what you see using binoculars - simply a disc identifying the object as a planet.
The middle image also shows a moon of Saturn - Titan (the largest moon of the planet). The rings are clearly visible using a 4” Newtonian reflector telescope.
As you increase magnification, you can detect the Cassini division - a gap between the rings. Also, the gap between the rings and the planet is more easily seen.
The bottom image was taken on a viewing night at Kitt Peak, Arizona. Our host was James Winsky and he sent me the photo of Saturn - as we saw it that night. We were able to see 8 moons of Saturn quite clearly. More divisions than just the main Cassini division were observed. The gap between the rings and the planet was very noticeable in the more powerful telescope. Also, you can see that the rings were almost at their maximum face-on view that we get from Earth. The Hubble Space Telescope sequence below gives you an idea of how the phase of Saturn alters:-
The images of Saturn were taken over the years 1996 on the left to 2000 on the right. Over Saturn’s 29.5 years orbit of the Sun, the appearance of the planet from Earth goes from edge on - looking under the rings - back to edge on - looking above the rings - and back to edge on again.
