M56 - A Modest Gem Between Giants
Messier 56 is a globular cluster tucked in a beautiful spot of the summer sky, lying between two of the season’s brightest showpieces: the bright star Albireo in Cygnus and the great globular Messier 57, the Ring Nebula, in Lyra. At magnitude 8.3, it isn’t as bright or rich as some of the more famous globulars, but its position along this stargazing “highway” makes it a rewarding stop for observers sweeping between Cygnus and Lyra on a clear summer night.

Through binoculars, M56 appears as a faint, hazy patch, a soft glow that stands out once you know where to look. A small telescope begins to show its compact, rounded form with a slightly brighter center, while medium and larger telescopes reveal the grainy sparkle of its stars at the edges, hinting at the richness within. Despite being one of the more modest Messier globulars, it rewards patient viewing and higher magnification.

M56 lies about 33,000 light-years away and contains hundreds of thousands of stars, many older than the Sun. It orbits through the Milky Way’s halo, making it one of the ancient building blocks of our galaxy. Its faintness compared to brighter clusters like M13 or M15 gives it a certain charm: it feels like a hidden treasure, reserved for those who take the time to seek it out.

In short, Messier 56 is “a little puff of starlight between the giants” — modest in brightness but rich in history and perfectly placed for summer stargazers exploring the skies of Cygnus and Lyra.


M56
Rating: 🟢 Solid CatchLevel: 🔵 EasyHow: When: Jun - Oct
🌟 Perfectly Placed in the Summer Sky
M56 sits almost exactly between Albireo, the colorful double star at the base of Cygnus, and the famous Ring Nebula in Lyra. This makes it easy to find and a fun target when you’re already in the neighborhood chasing brighter objects. Its location ensures that you’ll never waste time hunting — you’ll naturally pass by it on a summer sky sweep.
🌟 A Compact, Ancient Cluster
Although not the brightest globular, M56 is compact and tightly bound, containing hundreds of thousands of stars. At about 33,000 light-years away, it is one of the galaxy’s ancient residents, offering a chance to glimpse stellar populations that predate the Sun. Observing it connects you with the long history of the Milky Way itself.
🌟 Rewarding in Larger Telescopes
In binoculars and small scopes, M56 appears as a fuzzy glow, but medium to large telescopes begin to tease out individual stars, especially at the edges of the cluster. Its grainy appearance under magnification makes it a rewarding target for patient observers who like coaxing detail out of fainter globulars.
🌟 A Hidden Gem Among Showpieces
With the dazzling Ring Nebula and brilliant Albireo nearby, M56 is often overshadowed. But this makes it feel like a hidden gem — a lesser-known target that adds depth and variety to your observing session. Once spotted, it becomes a quiet favorite, a “resting place” of starlight amid the summer sky’s better-known wonders.

M56
The best way to star hop to Messier 56 is to use two of the summer sky’s brightest landmarks: Albireo, the beak of Cygnus the Swan, and the Ring Nebula (M57) in Lyra, between the two stars Sheliak and Sulfat in Lyra. Draw an imaginary line between these two -- M56 lies almost exactly at the midpoint.
Find the Summer Triangle which consists of the bright stars Vega (+0.02), Altair (+0.93) and Deneb (+1.33). Now find Albireo (+3.07), a striking double star visible to the naked eye at the tip of Cygnus’s beak. Then shift your field of view northwest toward Vega in Lyra, aiming for the bright star Sulafat (+3.25), which sits near the Ring Nebula.
M56 is roughly halfway between Albireo and Sheliak, making it easy to sweep up with binoculars or a low-power eyepiece. In binoculars, it will appear as a faint, round blur against the background stars, while a telescope at low magnification will confirm it as a small, compact globular.
Bonus Targets: Both Albireo and the Ring Nebula (M57) and hugely popular among stargazers. Both are just a short hop in opposite directions from M56. While Albireo is naked-eye and easy to find, M57 typically requires a telescope to find. Look halfway between Sheliak and Sulafat for a faint 'ghost-ring'. Then increase magnification.

Use Albireo and the Ring Nebula as Guides
To find M56, draw an imaginary line between Albireo in Cygnus and the Ring Nebula in Lyra. The cluster lies almost at the midpoint of this line, making it easy to locate once you know the landmarks.
Start with Low Power
Begin with a low-power eyepiece to pick up M56 as a faint, round glow. Its compact form makes it stand out from the surrounding star field, even if it looks like a soft patch at first glance.
Increase Magnification Slowly
Once you’ve found the cluster, increase magnification to start teasing out its grainy texture. Medium to large telescopes may reveal faint edge stars flickering into view, rewarding patient observing.
Seek Dark Skies
Because M56 is modest in brightness, it benefits from darker skies. Under suburban conditions it may look like little more than a faint smudge, but in a rural sky it transforms into a compact, concentrated ball of light.
Observe Nearby Showpieces
Pair your observation of M56 with Albireo’s colorful double star and the famous Ring Nebula. Seeing these three very different objects in one sweep of sky makes for a rich and varied observing session.
M56
Naked Eye
To the naked eye, Messier 56 is invisible. Even under the darkest skies, its modest brightness and compact size keep it hidden from unaided vision, overshadowed by the brighter stars of Cygnus and Lyra nearby.
⚠️ Binoculars
In binoculars, M56 appears as a faint, misty patch of light, barely distinguishable from the star field. It shows no structure or detail, but its soft glow marks it as something more than just another star.
Small Telescope
Through a small telescope, the cluster takes on the look of a rounded, fuzzy ball with a slightly brighter core. While no stars resolve clearly, the concentrated light hints at the thousands of suns packed within.
Medium Telescope
In a medium telescope, M56 grows more rewarding. The edges of the cluster begin to appear grainy, with faint individual stars popping into view at higher magnification. The central glow remains dense, emphasizing the contrast between the tight core and looser outskirts.
Large Telescope
With a large telescope, M56 transforms into a miniature sphere of glittering stars. Dozens of faint suns resolve across its edges, and the cluster gains depth and texture. While never as brilliant as larger globulars, it reveals itself as a compact jewel tucked between Cygnus and Lyra.
M56
Messier 56 is a modest globular cluster, and its visibility changes dramatically with sky quality. While it never rivals the brilliance of showpiece clusters like M13, it offers a rewarding view under the right conditions.
🟣 In Bortle 1–2 skies, M56 appears as a compact, concentrated cluster with a bright core and a halo that can be coaxed into grainy detail. Larger telescopes begin to resolve stars around its edges, giving it the sparkle of an ancient jewel.
🔵/🟢 In Bortle 3–4 skies, the cluster remains obvious but less detailed. The halo loses some of its richness, though the bright center still makes it an easy catch in a telescope. With careful observing, hints of individual stars can still be seen in larger instruments.
🟡 In Bortle 5–6 skies, M56 grows faint and subdued. It looks more like a hazy, unresolved patch with little texture, and most of its delicate outer structure is lost. It becomes a “checkpoint object” rather than a showpiece.
🟠 In Bortle 7+ skies, M56 is very difficult to observe. It may appear only as a dim smudge in a telescope, with no trace of structure or resolution. In heavy light pollution, the subtle beauty that makes it special all but disappears.
