Deep-Sky Objects Tonight — Sydney
Tonight from Sydney, the best-placed deep-sky showpiece is Ptolemy Cluster (M7), riding about 89° up in the south-western sky. Here's the full list of galaxies, nebulae and clusters worth hunting from Sydney tonight — and how dark a sky each one needs.
The Moon is nearly out of the way — dark skies for faint objects.
Best placed over Sydney tonight
Ranked by how high each climbs in tonight's dark sky from Sydney. The higher an object is, the less atmosphere you look through — and the better it shows.
A bright, sprawling star cluster low in the southern Milky Way — naked-eye from dark skies. In Scorpius.
A bright nebula in the heart of the Milky Way — superb in binoculars from a dark southern-sky view. In Sagittarius.
One of the brightest globular clusters, low in the south for northern observers. In Sagittarius.
A delicate nebula split by dark dust lanes, near the Lagoon in the rich Sagittarius star fields. In Sagittarius.
Home of the famous "Pillars of Creation"; the surrounding cluster is an easy binocular sight. In Serpens.
An edge-on galaxy with a dark dust lane like a hat brim — a small-telescope classic. In Virgo.
A dense, rich open cluster shaped like a flight of ducks — lovely in binoculars. In Scutum.
A compact, bright autumn globular cluster, easy to find off the Great Square of Pegasus. In Pegasus.
A bright planetary nebula, an easy and rewarding binocular and small-scope target. In Vulpecula.
A bright spring globular with half a million stars — a fine binocular and small-scope target. In Canes Venatici.
A tiny, perfect smoke ring — the glowing shell of a dying star; a small-telescope favourite. In Lyra.
The finest globular cluster for northern observers — a fuzzy ball of hundreds of thousands of stars. In Hercules.
A large, low-surface-brightness spiral — needs a genuinely dark, Moonless sky, then rewarding in binoculars. In Triangulum.
A swarm of stars filling a binocular field; a faint haze to the naked eye under dark skies. In Cancer.
The nearest big galaxy — a faint elongated smudge to the naked eye from a dark sky, the most distant thing most people ever see unaided. In Andromeda.
A face-on spiral with a companion — its spiral arms are visible in a modest telescope from a dark site. In Canes Venatici.
A tight, bright knot of blue stars — obvious to the naked eye, dazzling in binoculars. In Taurus.
A glowing stellar nursery in Orion’s sword — visible to the naked eye, stunning in binoculars, a showpiece in any telescope. In Orion.
