With binoculars you can see so much more in the night sky. Take our deep-sky tour and find out.
Whatever time of year you happen to be reading this, there are bound to be at least a few wonderful targets to see in the night sky tonight with binoculars.
Indeed, there are hundreds of astronomical bodies that a pair of binoculars will bring into view for you.
Not only will binoculars let you see many more objects than you can with the naked eye, but the detail and colour in those objects become a lot richer.
With binoculars, the Coathanger asterism in Vulpecula actually looks like a coathanger and the Orion Nebula becomes a fantastically detailed painting of light.
The Milky Way is no longer a tenuous glowing band, but a knotted tangle of stars, interspersed with mysterious dark patches.
Albireo goes from being an ordinary-looking star that marks the head of Cygnus to an exquisite binary juxtaposition of gold and sapphire.
And you can easily see galaxies by the light that left them millions of years ago, when our ancestors were thinking about leaving the trees.
Binoculars are still suitable even if you want to do ‘serious’ astronomy.
There are variable star observing programmes specifically for binoculars, and their portability makes them ideal for taking to the narrow track where a lunar graze or asteroid occultation is visible.
Alternatively, you could wrap up warm, lie back on your garden recliner and just enjoy the objects that the binoculars let you find as you cast your gaze among the stars.
Before you even realise it, you have begun to learn the sky and you’ll soon be able to navigate around it better than the entry-level Go-To telescope you nearly bought instead.
Best of all, you can have this complete observing system for two eyesfor less than the price ofone reasonably good telescope eyepiece.
In this guide we’ll go through 6 wonderful targets that are visible in the night sky through binoculars.
We’ll update the guide every month so you always have something new to observe, and as this archive grows you can scroll back through previous years of the current month and try and find those targets too.
Each binocular tour is made all the easier by downloading our PDF charts, the links for which you can find just at the top of each section below.
The tour charts are black on white, so you can read it under red light and avoid spoiling your night vision.

The Cosmic Question Mark
Use the chart at the link above to identify mag. 4.9 Nu (ν) Ceti and hold it at the bottom half of the field of view. You’ll see that it is the dot at the bottom of the 2.25°-long question mark asterism (an informal group of stars).
This is a good star-party object, both because of its shape and the colours of the fainter stars that make up the rest of the asterism.
The Pisces Parallelogram
If you follow a line up from mag. 2.0 Deneb Kaitos (Beta (β) Ceti; also known as Diphda) through mag. 3.5 Iota (ι) Ceti, you will find four stars of fifth magnitude (or so) that form a 3° x 1° parallelogram.
The northeast corner is blue-white 29 Psc, and diagonally opposite is orange 30 Psc; the other two corners of the parallelogram appear yellowish. See how the parallelogram appears empty: it contains only one star brighter than eighth magnitude.
T Ceti
Return to Deneb Kaitos and find the mag. 4.4 star 7 Ceti, 7° to the west. From there, go 2° to the southeast to T Ceti, the most westerly star in an equilateral triangle of sixth(ish)-magnitude stars, with a side of 1.5°.
T Ceti is a semi-regular variable star (mag. 5.0 to 6.9) with a period of 159.3 days. If you observe it every couple of weeks you should be able to notice this variation.
37 Ceti
The double star 37 Ceti lies nearly 2.5° west of mag. 3.6 Theta (θ) Ceti. Its components are 49 arcseconds apart, which theoretically should be an easy split, even with lower magnifications.
But the magnitude of the companion is only 7.9, which is 13 times less bright and can make splitting it a bit of a challenge. This is an optical double (a chance line-of-sight pairing), not a true binary star.
The Silver Coin Galaxy and NGC 288
With a good clear southern horizon, find the right-angled triangle of fifth-magnitude stars 5° south of Deneb Kaitos. Look below it for a rhombus of fainter stars. You’ll see the Silver Coin Galaxy (NGC 253) as an elongated glow about 1° beneath the rhombus.
Next look slightly less than 2° in the direction of Alpha (α) Sculptoris, where you should see the faint glow of the globular cluster NGC 288.
Melpomene
Asteroid 18 Melpomene has a very elliptical orbit with a period of 3.48 years, so approximately every seven years, when it’s near its perihelion, it appears brighter than usual.
It’s at peak brightness (mag. 8.2) at the beginning of November. To identify it, observe its environs over several nights to determine which ‘star’ moves relative to the others.

This month’s targets are all located in and around the constellation Cassiopeia.
Kurhah star field
The very white mag. 4.4 Kurhah (Xi (ξ) Cephei) is the most northerly and brightest star of a lovely group that stretches southward for about 3°. There are some very red stars like mag. 5.2 18 Cephei and, at the other extreme, hot blue mag. 5.1 19 Cephei.
Give yourself time to appreciate the sheer variety of what’s on show and look around for the other, fainter groups of colourful stars that lurk nearby.
U Cephei
Eclipsing variable star U Cephei lies midway between two white mag. 5.6 stars, 7.5° from mag. 2.0 Polaris (Alpha (α) Ursae Minoris), the North Star, in the direction of mag. 2.1 Gamma (γ) Cassiopeiae.
Its magnitude range is 6.8 to 9.2, a nine-fold variation in brightness over a period of 2.5 days which, coupled with it being circumpolar from the UK, makes it a suitable subject for newcomers to variable star observing.
35 Cassiopeiae
If you imagine that Segin (Epsilon (ε) Cassiopeiae) and Ruchbah (Delta (δ) Cassiopeiae) and Gamma (γ) Cassiopeiae are the apexes of a rhombus, you’ll see a triangle of stars near the fourth apex.
The one nearest to Segin is mag. 6.3 35 Cassiopeiae, a very white star, but can you detect any colour in its mag. 8.4 companion 1 arcminute to the north? This is a line-of-sight pairing, not a true binary star.
Cassiopeia triple cluster (NGC 654, 659, 663)
Look 1° to the east of the middle of an imaginary line joining Segin and Ruchbah and you’ll easily find the largest and richest of these clusters, NGC 663. Slightly less than 1° to the north-northwest is the brighter but smaller NGC 654.
The poorest of the trio is NGC 659, a tiny ghostly glow which may need averted vision, just on the NGC 663 side of mag. 5.8 44 Cassiopeiae.
The Owl Cluster, NGC 457
Start at Ruchbah and navigate 2° southwest to mag. 5.0 (Phi (φ) Cassiopeiae) and its mag. 7.0 companion 2 arcminutes further on. These are the owl’s eyes.
The Owl Cluster‘s body and wings are ninth and 10th-magnitude stars that span an area about 0.25° in the direction of Gamma Cassiopeiae. The brighter eye is not actually part of NGC 457; it lies half-way between us and the 8,000-lightyear-distant cluster.
The Muscleman Cluster
Identify the Perseus Double Cluster (NGC 884 and NGC 869) and from the part nearest to Cassiopeia follow a 2° chain of eighth-magnitude stars north to Stock 2, the Muscleman Cluster.
This gets its name from the brighter stars having the form of a stick-man in muscle-flexing body-builder pose, ripping this star-chain away from the Double Cluster.

M2
Charles Messier described the globular cluster M2 as “a nebula without stars”. You’ll find it due north of Sadalsuud (Beta (β) Aquarii) and due west of Sadalmelik (Alpha (α) Aquarii).
It’s obvious in a star-sparse region of sky; even in small binoculars you should be able to see this 38,000-lightyear-distant glow. If you use averted vision, it will appear to grow slightly and may appear very slightly oval in shape.
Σ2809
From M2, head slightly more than a degree east-northeast to a mag. 6.2 star. This is the brighter component of a double-star system, Struve 2809.
Seeing the fainter companion is a good test of both 10×50 binoculars and your observing technique, because it’s a mere 31 arcseconds to the south-southeast and shines at only mag. 9.3. Don’t expect to see it consistently; it may ‘fade’ in and out of visibility.
Saturn and Titan
Saturn is the brightest object in the area covered by the chart, so is easy to locate. You won’t see the rings in 10×50 binoculars, but you can see the brightest moon, Titan, which shines at mag. 8.4.
Its period of orbit around Saturn is nearly 16 days and its angular distance from the planet ranges between 0.5 and 3 arcminutes, so the second-largest moon in the Solar System is quite easy to spot. ο
The Saturn Nebula, NGC 7009
If you want a good binocular observing challenge in British skies, this is a top candidate. Fortunately,
it’s very easy to locate, 1.3° due west of mag. 4.5 Nu (ν) Aquarii.
It appears as a slightly defocused star but, because it’s only about 0.4 arcminutes across, at this magnification you’ll not be able to see the elongation that Lord Rosse detected when he gave it its common name.
8 Flora
Here’s a rare opportunity to spot asteroid 8 Flora in binoculars. It starts the month at mag. 8.5, 6.7° south of Saturn and fades by a bit more than half a magnitude as it tracks 5° west-southwest during the month. It will be hard to identify against the background stars, so you’ll need to observe on several occasions to detect which of these ‘stars’ moves in relation to the others. ο SEEN IT
6. M30
If you plan to do a Messier Marathon (observing all 110 Messier objects between dusk and dawn) next spring, M30 is one you need to be confident of finding, being the difficult last object in a lightening dawn twilight sky. Autumn evenings are a very good time to start this practice. You’ll find it half a degree from mag. 5.2 41 Capricorni in the direction of mag. 3.7 Zeta (ζ) Capricorni. ο SEEN IT

M11, the Wild Duck Cluster
Our tour of the southern portion of the Milky Way begins with one of the densest open clusters, M11, the Wild Duck Cluster. You’ll find it 2° southeast of mag. 4.2 Beta (β) Scuti, spanning about 0.25° of sky.
In 10×50 binoculars, the cluster appears as a bright, slightly wedge-shaped glow. Were it not so rich, you may have had trouble identifying it against the Scutum Star Cloud, the densest part of the Milky Way.
M26
If you put mag. 3.8 Alpha (α) Scuti at the northwest of your field of view, open cluster M26, also known as NGC 6694, will be southeast of centre. Although it is only mag. 8.0, M26 is easy to find.
Look for a glowing kite shape which has the unusual feature of being less bright in the middle, due to some intervening interstellar dust, so what you see is an open cluster with a tiny dark nebula in the middle.
M24, the Sagittarius Star Cloud
M24 lies slightly more than half-way from mag. 4.7 Gamma (γ) Scuti to mag. 3.8 Polis (Mu (µ) Sagittarii). It is a bright patch of light that is easily visible to the naked eye and which has even been mistaken for a cloud just above the horizon.
It is a remarkably good object in 10×50 binoculars, in which nearly 1,000 stars are resolved in a single field of view!
M25 and U Sagittarii
If you navigate 4.5° south from Gamma Scuti, you should easily find the bright (mag. 4.6) open cluster M25, showing distinctly against the background Milky Way, with eight or so stars resolved against a grainy background.
It’s easier to distinguish the cluster from the background Milky Way in small binoculars than in large ones. The brightest star in the cluster is the Cepheid variable, U Sagittarii (which varies from mag. 7.2 to 6.5).
M23
M23 is just over half-way from mag. 3.5 Xi (ξ) Serpentis to Polis, but may be difficult to distinguish from the rich background of the Milky Way.
This bright, oval (15×27 arcminutes) open cluster is lovely in 70mm binoculars, which reveal about a dozen stars in the shape of a lower-case letter alpha (α) against the background glow of another 140 fainter stars.
M8, the Lagoon Nebula
Look for M8, the Lagoon Nebula, 6° west-northwest of mag. 3.0 Kaus Borealis (Lambda (λ) Sagittarii). It is visible to the naked eye if it’s high in a reasonably dark and transparent sky.
With 10x50s you’ll resolve more than half a dozen stars and reveal some of the surrounding nebulosity (NGC 6523) they illuminate, as well as the denser cluster of stars to the east of the main nebulosity.

1 – Sadr, the Heart of Cygnus
The mag. 2.2 star Sadr (Gamma (γ) Cygni) is sometimes called ‘the heart of Cygnus’, but it is really only part of the story. If you look carefully, you’ll notice that Sadr is merely the point of inflexion in a cardioid-shaped asterism of 11 mostly 6th-magnitude stars.
It has a diameter of a little less than 2° and offers a wide variety of colours, from deep orange through yellow and white, to an intense blue-white.
2 – NGC 6940
The open star cluster NGC 6940 deserves to be far better known. Use the chart to identify mag. 4.0 41 Cygni and mag. 4.9 30 Vulpeculae and you’ll find NGC 6940 between them, appearing like an oval patch of light that extends to the same apparent diameter as the Moon.
As you study the 2,700-year-old glow, you should be able to resolve eight or so stars of this very pretty cluster, depending on your sky conditions.
3 – The Dumbbell Nebula, M27
Our next stop is the easiest planetary nebula for binoculars, visible even in moderately light-polluted skies. If you place Gamma (γ) Sagittae at the south of a 5° field of view, the mag. 7.4 Dumbbell Nebula will be just north of centre, looking like a tiny luminous cloud.
Initially it will appear rectangular, but with patience you should make out the narrowing in the middle that gives it its common name.
4 – Barnard’s E Nebula
In a dark, transparent sky, this pair of dark nebulae, B142 and B143, which you will find 1° west of mag. 2.7 Tarazed (Gamma (γ) Aquilae) is easy to identify because of the rich Milky Way starfield against which it lies.
These agglomerations of obscuring gas and dust will appear to you as an uppercase ‘E’ or an underlined ‘C’, depending on sky clarity. The easiest bit to see is the middle bar of the E.
5 – Eta Aquilae
What was the first Cepheid variable star to be discovered? Answer: Eta (η) Aquilae (mag. 3.5 to 4.4) – not Delta (δ) Cephei, the star that gave its name to this class of variables.
Edward Piggott found variability in the former a month before John Goodricke found it in the latter. In 1912, Henrietta Leavitt discovered their period-luminosity relationship – the ‘standard candles’ Edwin Hubble then used to measure galactic distances.
6 – M15
Easy globular cluster M15 is one 15×70 field of view northeast of Delta (δ) Equulei. Don’t expect it to look even half as wide (18 arcminutes) as the published data suggests.
Most of its stars are in a core so dense that even the Hubble Space Telescope can’t resolve it, and only the central 7 arcminutes is visible in 70mm binoculars. ο SEEN IT

1 – M5
Let’s start with a fine globular cluster, M5, immediately north-northeast of mag. 5.0 5 Serpentis. It contains mostly Population II stars, which are among the oldest stars that we can see.
They are thought to be more than 12 billion years old, which suggests that they formed very soon after our Galaxy did. In 10×50 binoculars, you should notice that M5 brightens towards the centre, exactly like a comet does.
2 – Zubenelgenubi
In antiquity, the stars of Libra, the only non-living zodiac constellation, represented the claws of Scorpius, and the common name of mag. 2.7 Alpha (α) Librae, Zubenelgenubi, means ‘southern claw’ (the northern claw is mag. 2.6 Zubenelschamali (Beta (β) Librae).
Zubenelgenubi is a nice easy binocular double star. Binoculars easily reveal the mag. 5.2 companion 3.5 arcminutes away.
3 – Delta Librae
You’ll find the variable (mag. 5.8 to mag. 4.4) Delta (δ) Librae 8° north of Zubenelgenubi. It’s an eclipsing binary star (a pair of stars orbiting their common centre of mass) in which the drop in brightness, which lasts for about six hours, occurs as the dimmer star occults the brighter one.
The orbital period is 2.3 days, so even during short summer nights you’ll have several opportunities to notice the magnitude change.
4 – Xi1/Xi2 and 17/18 Librae
Midway between Delta Librae and Zubenelgenubi lie two optical double stars (not gravitationally bound binaries). Mag. 5.8 Xi1 (ξ1) and mag. 5.4 Xi2 (ξ2) Librae are separated by 0.75°.
Half a degree northeast of Xi2 is the other pair, mag. 6.6 17 Librae and mag. 5.8 18 Librae, which are nearly 10 arcminutes apart. There is about 50 lightyears between 17 and 18, and more than four times that between Xi1 and Xi2.
5 – M4
M4 is nearly 1.5° west of bright orange mag. 1.0 Antares (Alpha (α) Scorpii). It is only 7,000 lightyears away, making it appear rather loose, and is one of the few globular clusters in which you may be able to discern some structure with 15×70 binoculars.
M4 lies on the edge of the Milky Way, within a beautifully rich, colourful star-field that is more pleasing in binoculars than in a scope.
6 – Rho Ophiuchi
If you navigate 3° north from M4, you’ll find mag. 5.0 Rho (ρ) Ophiuchi. It is the bright component of a triple star, whose seventh-magnitude companions are 2.5 arcminutes to the north and west, respectively.
If you have an exceptional southern horizon sky and fancy a challenge, see if averted vision enables you to detect a slight brightening surrounding the star.

1 – M53
A degree northeast of mag. 4.3 Diadem (Alpha (α) Comae Berenices), you’ll find a small misty patch which appears to grow in size and brightness if you centre it in the field of view then avert your gaze back to Diadem.
The apparent changes, which are typical of globular clusters, demonstrate the difference between direct and averted vision. Practice this technique; you’ll need it later when we seek out the galaxies in Markarian’s Chain
2 – FS Comae
Navigate to a point half-way between Diadem and mag. 4.2 Beta (β) Comae Berenices, then another degree to the west to an orange star, FS Comae, shining somewhere around mag. 6.
The magnitude of this semi-regular variable star varies between mag. 6.1 and 5.3, with a period of 55–58 days. Analysis of the star’s spectrum reveals variations in radial velocity of the star’s surface, which indicates that its variability is due to pulsations in size.
3 – 28 &29 Comae
Head 5° northwest of mag. 2.8 Vindemiatrix (Epsilon (ε) Virginis) to a pair of white stars separated by half a degree and orientated roughly north–south. The southerly one is mag. 6.4 28 Comae, brightest of a little parallelogram of stars.
Mag. 5.7 29 Comae is the brightest of a triple star group. The brighter (mag. 8.6) companion is 5 arcminutes back towards 28 Comae, and the fainter (mag. 9.9) one is an arcminute closer.
4 – Ceres
Ceres was discovered by Guiseppe Piazzi on the first day of the 19th century and is the only dwarf planet visible in standard binoculars.
It fades from mag. 7.8 to mag. 8.4 during the month, but should be easiest to detect around mid-month when the Moon is out of the way and it is 2.2° east of mag. 2.1 Denebola (Beta (β) Leonis).
5 – M49
Locate mag. 4.9 Rho (ρ) Virginis and place it on the northeast of your field of view. On the opposite side you should find a pair of sixth-magnitude stars, a little more than a degree apart and orientated southeast–northwest.
M49 is the small, slightly oval patch of light between these two. Use averted vision to see how many more galaxies you can detect in this region of sky.
6 – Markarian’s Chain
TTheis chain of galaxies known as Markarian’s Chain, which you may already have detected north of M49, lies almost exactly half way between Vindemiatrix and Denebola.
Starting with M84 and M86, you should be able to identify at least the seven brightest galaxies in the chain.

1 – The Double Cluster
Half way between mag. 2.6 Ruchbah (Delta (δ) Cassiopeiae) and mag. 2.9 Gamma (γ) Cassiopeiae you will find a close pair of open clusters. These are known as the Double Cluster.
In a rural sky, you can see them with your naked eye as a distinctly elongated smudge of light, but binoculars will reveal two little concentrations of stars. Those stars are intrinsically extremely bright: if the Sun was there, it would be too faint for you to see it in binoculars!
2 – Melotte 15
If you imagine that mag. 3.3 Segin (Epsilon (ε) Cassiopeiae) and mag. 4.6 Iota (ι) Cassiopeiae are two corners of an equilateral triangle, Melotte 15 is the third corner.
In 10×50 binoculars, you’ll see a large (20-arcminute) glow with a handful of brighter stars forming a V shape. If you have a UHC filter to hold over an eyepiece, you might see the nebulosity (IC1805, the Heart Nebula) that surrounds, and gave birth to, the cluster.
3 – Markarian 6
Markarian 6 lies slightly less than 1° to the south-southwest of Mel 15. It’s quite easy to miss, so we use larger binoculars. What you should see is an arrow of half a dozen ninth-magnitude stars pointing southwards.
Owing to its faintness compared to Mel 15, you might assume it is much further away, but at 1,600 lightyears it is actually just under a quarter of the distance.
4 – Pazmino’s Cluster
If you pan slightly more than 1.5° due west from mag. 4.3 CS Camelopardalis, you will find an unremarkable little trapezium of seventh and eigth-magnitude stars. This is Stock 23, also known as Pazmino’s Cluster.
Your binoculars should reveal that this is much more than a trapezium and you may be able to resolve about half a dozen stars against a faintly glowing patch of sky about 10 arcminutes in diameter.
5 – Kemble’s Cascade
On spring evenings, Kemble’s Cascade is near-horizontal in the sky, so this line of eighth-magnitude stars, with a brighter fifth-magnitude one in the middle, looks more like a wristwatch or bracelet opened out against the sky than a tumbling cascade.
To find it, extend a line from mag. 2.3 Caph (Beta (β) Cassiopeiae) to Segin the same distance to the central bright star.
6 – Beta Cam
You can see mag. 4.0 Beta (β) Camelopardalis with the naked eye, and its mag. 7.4 companion, which lies 84 arcseconds southwest is easy to distinguish, even in small binoculars.
Beta Cam is a yellow supergiant in transition between being a hot new blue star and a much cooler red supergiant. It sometimes flashes, probably due to the equivalent of huge solar flares.
