Skywatchers in the UK looking to the south-southwest at dusk on Monday, 17 September can see the waxing gibbous Moon just 1¾ degrees to the upper left of Saturn, the pair fitting comfortably in the same field of view of binoculars and small telescopes magnifying 25× or less. This is also a good night for spotting Titan, Saturn’s largest and brightest moon.
Three naked-eye planets – Mars, Jupiter and Saturn – grow in prominence in the dawn sky this month. If you wish to identify them for yourself, let the waning Moon be your celestial guide from 7–11 March. We also show you what to look for in binoculars and telescopes.
Observers in the UK will find Venus almost directly below the three-day-old Moon low in the south-southwest in deep twilight an hour after sunset on 3 December. The pair will fit in the same field of view of most 8x and 7x binoculars, but a deep-sky treat lies in store for telescope users.
