The Moon is Earth’s only natural satellite, the brightest object in our night sky after the Sun, and—in my two decades behind a telescope—the single best target for anyone learning astrophotography. I’m Hamza Touhami, an astrophotographer since 2008 who runs a remote imaging rig at Deepsky Chile (an Alluna 12.5″ Ritchey-Chrétien on a Paramount MX+), and the Moon is where I tell every beginner to start. It is bright, forgiving, endlessly detailed, and it rewards patience faster than any deep-sky object ever will.
Quick answer: The Moon is Earth’s only natural satellite, orbiting roughly 384,400 km away. It likely formed when a Mars-sized body called Theia struck the early Earth. Its phases come from the changing sunlit angle we see, not Earth’s shadow. The best time to photograph it is along the terminator, not at full Moon.
This guide covers how the Moon formed, why its phases happen, the difference between the near and far sides, what maria and craters actually are, eclipses and supermoons, and—most usefully—a practical, field-tested workflow for observing and photographing the Moon in 2026. If you want to plan your framing, our telescope field of view calculator shows exactly how the Moon fits your camera and scope.
How did the Moon form?
The leading explanation is the giant-impact hypothesis: about 4.5 billion years ago, a Mars-sized protoplanet that scientists call Theia collided with the proto-Earth. The oblique impact blasted molten debris into orbit, and that material accreted just beyond Earth’s Roche limit to form the Moon.
This theory is favored because the Moon’s composition closely mirrors Earth’s mantle, yet it is depleted in volatile elements and iron—exactly what you’d expect from material that was vaporized and re-condensed in a high-energy collision. Apollo sample isotopes match Earth so tightly that any competing model has to explain that similarity.
Why this matters for what we see
The impact origin explains why the Moon has a small iron core and a relatively low density. It also set up the large, dark plains we see today, because the early Moon stayed molten long enough for heavy material to differentiate and for later lava flows to fill enormous impact basins. That history is written across the surface every clear night.
Why does the Moon have phases?
Moon phases happen because we see different fractions of the Moon’s sunlit half as it orbits Earth—they are not caused by Earth’s shadow. Half the Moon is always lit by the Sun; what changes is the angle between the Sun, Earth, and Moon, which controls how much of that lit half faces us.
One common confusion: people assume the dark part of the Moon is in Earth’s shadow. It isn’t. Earth’s shadow only touches the Moon during a lunar eclipse. The rest of the time, the unlit portion is simply the part of the Moon’s own night side turned toward us.
The eight phases in order
- New Moon — the lit side faces away; the Moon is essentially invisible.
- Waxing Crescent — a thin sliver grows in the evening sky.
- First Quarter — half-lit; rises around midday, sets around midnight.
- Waxing Gibbous — more than half, still growing.
- Full Moon — fully lit; rises at sunset.
- Waning Gibbous — shrinking from full.
- Last Quarter — the other half lit; rises near midnight.
- Waning Crescent — a thin sliver before dawn.
The full cycle—new Moon to new Moon—takes about 29.5 days. This is the synodic month, and it’s slightly longer than the 27.3-day orbital period because Earth is also moving around the Sun, so the Moon has to travel a little farther to line up the same way again.
| Phase | What you see | Best for |
|---|---|---|
| New Moon | Not visible | Deep-sky imaging (dark skies) |
| Waxing Crescent | Thin evening sliver | Earthshine, dramatic terminator |
| First Quarter | Half lit, evening | Best lunar detail — crisp shadows |
| Full Moon | Fully lit disc | Wide-field landscape shots only |
| Last Quarter | Half lit, pre-dawn | Excellent crater relief |
What is the difference between the near side and far side?
The near side is the hemisphere that always faces Earth; the far side is the one we never see directly from the ground. This happens because the Moon is tidally locked—its rotation period exactly equals its orbital period, so the same face is permanently turned toward us.
The two hemispheres look strikingly different. The near side is dominated by the large dark maria, while the far side is rugged, heavily cratered, and almost devoid of those smooth plains. The far side’s crust is thicker, which likely prevented as much lava from flooding its basins. It is not the “dark side”—both hemispheres receive sunlight equally over a lunar month.
Libration: seeing a little extra
Although the Moon is tidally locked, a wobble called libration lets us glimpse about 59% of the surface over time. The Moon’s slightly elliptical orbit and tilted axis mean it nods and rocks gently as seen from Earth. For imagers, libration is worth tracking because it briefly tips features near the limb into better view—Mare Orientale is the classic example.
What are maria and craters?
Maria (Latin for “seas”) are the large, dark, smooth plains of ancient solidified basaltic lava; craters are the round impact scars left by asteroids and comets over billions of years. Early astronomers mistook the maria for actual oceans, and the name stuck.
The maria formed when massive impacts punched through the crust and dark lava welled up to fill the basins roughly 3 to 3.5 billion years ago. The brighter, rougher regions between them are the older lunar highlands. Because the Moon has no atmosphere or active weather, its craters and rays are preserved with astonishing sharpness—which is exactly why it photographs so well.
Features worth hunting
- Copernicus — a young, terraced crater with a bright ray system.
- Tycho — in the southern highlands, with rays stretching across the disc at full Moon.
- Mare Tranquillitatis — the Sea of Tranquility, near the Apollo 11 landing site.
- Apennine Mountains — a dramatic mountain arc bordering Mare Imbrium.
- Plato — a dark-floored crater that stands out beautifully near the terminator.

What are eclipses and supermoons?
A lunar eclipse happens when Earth passes directly between the Sun and Moon, casting its shadow on the lunar surface; a supermoon is a full Moon that occurs near the Moon’s closest approach to Earth, making it appear slightly larger and brighter. Both are easy, rewarding targets.
During a total lunar eclipse the Moon doesn’t vanish—it turns a coppery red, the famous “Blood Moon,” because sunlight bent through Earth’s atmosphere still reaches it. In 2026 a total lunar eclipse falls on March 3, visible from the Americas, with a partial lunar eclipse on August 28. A total solar eclipse—which involves the Moon passing in front of the Sun—occurs on August 12, 2026.
2026 supermoons
2026 brings three supermoons—on January 3, November 24, and December 23. The December 23 full Moon is the closest of the year at about 356,740 km, the nearest full Moon since 2019. A supermoon looks roughly 7% wider and noticeably brighter than an average full Moon, though the difference is subtle to the naked eye. For eclipse and Sun-related events, our developing Sun guide and meteor shower calendar round out the observing year.
How do you photograph the Moon?
The best way to photograph the Moon is to shoot along the terminator—the line dividing lit and unlit areas—at first or last quarter, where low-angle sunlight casts long shadows and reveals maximum crater relief. The full Moon, despite being the brightest, is actually the worst for detail because the flat, head-on light washes out texture.
This is the single most important lesson I share with beginners. People wait for the full Moon and come away disappointed by a flat, featureless disc. Shoot two or three nights before or after full—or better, at quarter phase—and the same telescope suddenly delivers dramatic, three-dimensional terrain.
Single-shot versus lucky imaging
There are two core techniques, and the right one depends on your gear and goals.
- Single-shot (DSLR/mirrorless): Attach a camera to your telescope at prime focus, or use a long telephoto lens (300mm+). One well-exposed frame can produce a sharp full-disc image. This is the fastest route to a satisfying result.
- Lucky imaging (planetary camera): Record a short video of a few thousand frames with a high-speed camera, then use software like AutoStakkert! to keep only the sharpest frames and stack them. This beats atmospheric turbulence and yields the crisp, high-resolution close-ups you see from serious lunar imagers.
For full-disc work I lean on single-shot frames; for crater close-ups I always use lucky imaging. Even from my remote RC at Deepsky Chile, stacking sharp moments out of a video clip consistently outperforms any single exposure when seeing conditions wobble.
Gear and exposure settings
You don’t need a huge instrument. A small refractor or any telescope from 60mm aperture upward will show craters beautifully. Here’s the practical starting point I recommend:
- ISO: 100–200 (the Moon is bright; keep noise low).
- Shutter speed: roughly 1/125 to 1/250 second for a full Moon; lengthen toward a thin crescent.
- Aperture (lens shots): f/8 to f/11 for a sharp result.
- Focus: manual, magnified live view on a crater edge—never autofocus.
- Stability: a solid tripod or tracking mount, plus a remote shutter or 2-second timer to kill vibration.
Shoot in RAW so you can recover contrast and sharpen in post. A tracking mount helps a great deal at high magnification, but for full-disc shots a sturdy tripod is enough. To work out whether the Moon will fill your frame or float in it, plug your setup into the field of view calculator, and use our astrophotography calculator to check focal length, sampling, and exposure together.
Processing your lunar shots
Light processing transforms a good capture into a great one. For stacked images, run the output through wavelet sharpening (RegiStax or PixInsight’s MultiscaleMedianTransform) to pull out fine detail. For single shots, modest contrast, a touch of unsharp mask, and careful highlight control are usually all you need. Resist over-sharpening—harsh halos around craters are the telltale sign of a heavy hand.
When is the best time to observe the Moon?
The best time to observe the Moon is during the first or last quarter, when the terminator slices across the disc and shadow detail is at its richest. A waxing crescent in the evening is also gorgeous, often showing “earthshine”—the faint glow on the unlit side reflected from Earth.
Plan around the phase, not just the clearest night. Check the Moon’s altitude too: higher in the sky means you look through less turbulent atmosphere, so detail holds together better. A night of steady seeing at quarter phase beats a crystal-clear full-Moon night every time for detail work.
A simple first session
- Pick a night near first quarter and set up before dark.
- Find the Moon, then focus carefully at high magnification on a crater near the terminator.
- For visual observing, start at low power and increase magnification until detail softens, then back off.
- For imaging, capture both a full-disc frame and a short close-up video clip.
- Note the date and libration so you can compare features over a full lunar month.

Frequently asked questions
Why does the Moon look bigger near the horizon?
The Moon doesn’t actually change size near the horizon—this is the “Moon illusion,” a trick of human perception. When the Moon sits low next to trees, buildings, and the landscape, your brain judges it as larger by comparison. Measure it with a camera and it’s the same size as when it’s overhead.
Can I photograph the Moon without a telescope?
Yes. A DSLR or mirrorless camera with a 300mm or longer telephoto lens on a tripod captures a recognizable, crater-dotted Moon. Even modern smartphones with optical zoom can grab a respectable shot. A telescope simply lets you reach far higher magnification and resolve fine detail like crater terraces and rilles.
What causes a Blood Moon?
A Blood Moon is a total lunar eclipse, when Earth passes between the Sun and Moon and casts its shadow on the lunar surface. The Moon glows red rather than going black because sunlight is refracted through Earth’s atmosphere, which filters out blue light and bends the remaining red light onto the Moon. The next one for the Americas is March 3, 2026.
Why is the full Moon bad for astrophotography of detail?
At full Moon, sunlight hits the surface head-on, so shadows vanish and the terrain looks flat and washed out. Crater walls, mountain ranges, and rilles only show their relief when sunlight strikes them at a low angle—which happens along the terminator near the quarter phases. That’s why experienced lunar imagers avoid full Moon for close-up work.
How far away is the Moon and is it moving?
The Moon orbits at an average distance of about 384,400 km, but it’s slowly drifting away from Earth at roughly 3.8 centimeters per year due to tidal interaction. Over hundreds of millions of years this gradually lengthens Earth’s day, too—though on any human timescale the Moon’s distance and appearance are effectively constant.
