This one takes a small telescope and a good night. North of the equator it is best placed in the summer.

Look in the constellation Serpens.
What it takes: The star cluster at its centre is an easy small-telescope target; the surrounding nebulosity needs dark skies and a filter.
Finding it: The central star cluster M16 sits in Serpens, near the Milky Way’s brightest part.
On the sky it is about 35 arcminutes across, where the full Moon is 30.
Its nearest bright landmark is Nunki, in Sagittarius — 15.1° away, or about 1.5 fists at arm’s length.

From the Southern Hemisphere, look in the winter.
It rises above the horizon everywhere south of latitude 76.2° north.
This is the Earth. Where the globe is clear, this object climbs high in the sky; the darker the shading, the lower it stays; where the globe is black, it never rises at all. If the globe has no shading, it does not matter where on Earth you are.
A faint, ghostly glow — darker skies show much more.
