Best placed over Lisbon tonight
Ranked by how high each climbs in tonight's dark sky from Lisbon. The higher an object is, the less atmosphere you look through — and the better it shows.
The finest globular cluster for northern observers — a fuzzy ball of hundreds of thousands of stars. In Hercules.
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 tiny, perfect smoke ring — the glowing shell of a dying star; a small-telescope favourite. In Lyra.
A face-on spiral with a companion — its spiral arms are visible in a modest telescope from a dark site. In Canes Venatici.
A large, low-surface-brightness spiral — needs a genuinely dark, Moonless sky, then rewarding in binoculars. In Triangulum.
A bright spring globular with half a million stars — a fine binocular and small-scope target. In Canes Venatici.
A tight, bright knot of blue stars — obvious to the naked eye, dazzling in binoculars. In Taurus.
A bright planetary nebula, an easy and rewarding binocular and small-scope target. In Vulpecula.
The wreckage of a supernova seen in 1054 AD — a faint glow needing a telescope and a dark sky. In Taurus.
A swarm of stars filling a binocular field; a faint haze to the naked eye under dark skies. In Cancer.
A compact, bright autumn globular cluster, easy to find off the Great Square of Pegasus. In Pegasus.
A bright spiral galaxy near the Big Dipper, paired with M82 in the same binocular field. In Ursa Major.
A glowing stellar nursery in Orion’s sword — visible to the naked eye, stunning in binoculars, a showpiece in any telescope. In Orion.
A dense, rich open cluster shaped like a flight of ducks — lovely in binoculars. In Scutum.
An edge-on galaxy with a dark dust lane like a hat brim — a small-telescope classic. In Virgo.
Home of the famous "Pillars of Creation"; the surrounding cluster is an easy binocular sight. In Serpens.
A delicate nebula split by dark dust lanes, near the Lagoon in the rich Sagittarius star fields. In Sagittarius.
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.
