Saturn and its rings always look wonderful when viewed through a telescope, but this evening provides a great opportunity to target the planet’s moons through an 8-inch or larger instrument.Two inner moons — 12th-magnitude Enceladus and 13th-magnitude Mimas — reach greatest eastern elongation within an hour of each other and show up under good viewing conditions.The viewing is especially good tonight because the bright glare of Saturn's rings normally masks these moons when they lie closer to the planet.You can find the two moons tonight standing just beyond the rings’ edge halfway between the 10th-magnitude satellites Dione and Tethys.Plan observing targets for every night by catching up with Astronomy's The Sky This Week column
