Look no further for quality optics at a great price, the Nikon Aculon A211 binoculars offer BaK-4 prisms, 50mm objective lenses and 10x magnification. It's hard to find such a top-quality pair of binoculars that are also affordable. Read our Nikon 10x50 Aculon A211 binoculars review.

The silvery curl of the crescent moon will hang low over the western horizon as the sun slips from view, less than 5 degrees to the upper left of the Beehive star cluster, which is also known as Messier 44, or Praesepe.

Jupiter will shine brightly about 20 degrees to the lower right of the moon, while Venus and Mercury form a diagonal line beyond. Mercury — the lowest of the planetary trio — will sit less than 5 degrees above the horizon. You'll need a clear view to the west, but even then you may struggle to spot it in the yellow glow of the retreating sun.

Both the moon and the Beehive Cluster will fit neatly in the field of view of a pair of 10X50 binoculars, which help reveal the brightest of its young stars in the waxing glow of the 36%-lit lunar disk.

A small backyard telescope will bring a plethora of diverse craters and dark lunar seas into view. Look out for Theophilus crater, which sits close to the line separating night from day — known as the terminator — and the Piccolomini impact site, which scars the lunar surface further to the south.

Both craters feature prominent central peaks formed from rock that rebounded inwards following the violent impact that heralded their creation. Their terraced eastern walls will also appear filled with shadow on May 21, making for a dramatic sight.

The moon will gently drift away from M44 as the hours wear on, before finally setting below the horizon in the early hours of May 22.
