M30 is simply 3° due west of Vesta, straightforward to get throughout the similar binocular (or finder scope) area of view.
Additionally in Capricornus is mighty Saturn, which glows at magnitude 0.3. The ringed planet is 5° west of Deneb Algedi and 1° east of 4th-magnitude Iota (ι) Capricorni. By a telescope, its disk stretches 18″ throughout, whereas its rings span some 42″ alongside their lengthy axis. Look additionally for magnitude 8.5 Titan, which sits about 1′ to Saturn’s southwest tonight.
