Telescope Mounts Explained: Alt-Azimuth vs. Equatorial
A telescope mount is the part that holds your telescope steady and lets you aim it, and the two main telescope mount types are alt-azimuth (moves up/down and left/right, like a camera tripod) and equatorial (tilts to match Earth’s axis so you can follow the sky with one smooth motion). Alt-azimuth mounts are simpler and better for casual viewing and beginners, while equatorial mounts make tracking objects and astrophotography much easier once you learn to set them up.
If you’ve been shopping for a first telescope, you’ve probably noticed that the mount often costs as much as the telescope itself — and for good reason. A shaky or confusing mount is the number-one reason beginners give up. This guide breaks down the mount types in plain English so you can pick the right one with confidence.
What is a telescope mount, and why does it matter so much?
The mount is the mechanical base that supports the telescope tube and lets you point it at the sky. It usually sits on a tripod (or, in the case of a Dobsonian, a wooden base that sits on the ground). The mount does two jobs: it holds everything rock-steady so the image doesn’t jiggle, and it lets you move smoothly to find and follow objects.
Here’s the part beginners underestimate: at high magnification, the sky appears to drift surprisingly fast because the Earth is rotating. A good mount lets you nudge the telescope to keep an object centered. A bad one shakes for several seconds every time you touch it, turning Saturn into a blurry, bouncing smudge. That’s why we always tell first-time buyers to spend a little more on a solid mount than on extra aperture. You can browse everything in one place in our Mounts & Tripods collection.
What is an alt-azimuth mount?
An alt-azimuth (or “alt-az”) mount moves in two intuitive directions: altitude (up and down) and azimuth (left and right, side to side). It works exactly the way a photo tripod does, which is why almost everyone finds it easy on the very first night.
Alt-azimuth mounts are lightweight, quick to set up, and forgiving. Point at the Moon, a planet, or a bright star and you’re observing within seconds — no alignment ritual required. The trade-off is tracking: because the sky appears to move in a curved, diagonal arc, keeping an object centered at high power means constantly adjusting both knobs at once. For relaxed viewing that’s no problem, but it makes long-exposure astrophotography impractical.
A great example is the Explore Scientific Twilight I Alt-Azimuth Mount & Tripod, a smooth, sturdy manual alt-az that carries small-to-medium telescopes and is ideal for grab-and-go nights.
The most famous alt-azimuth design of all is the Dobsonian, which pairs a big reflector tube with a simple rocker base. If you want maximum aperture for your money with the simplest possible aiming, read our guide to Dobsonian telescopes explained.
What is an equatorial mount?
An equatorial (EQ) mount is tilted so that one of its axes — the polar axis — points at the celestial pole (near the North Star, Polaris, for those of us in the United States). Once it’s aligned, the sky’s apparent motion is matched by turning a single axis. That means you can follow a planet or galaxy across the sky with one slow-motion control (or a small motor), instead of wrestling two knobs at once.
This is the mount’s superpower: effortless tracking. It’s what makes an equatorial mount the standard choice for astrophotography, where the camera shutter may stay open for minutes and even the slightest drift ruins the shot. The catch is a learning curve. You have to level the tripod, set it for your latitude, and perform a rough “polar alignment” before observing. The counterweights also make EQ mounts heavier and bulkier than an equivalent alt-az.
For a beginner-friendly manual option, the Explore Scientific EXOS Nano Equatorial Mount & Tripod is a lightweight, affordable way to learn EQ tracking with a small telescope. You’ll find the full range in our Telescope Mounts collection.
Alt-azimuth vs. equatorial: side-by-side comparison
| Feature | Alt-Azimuth Mount | Equatorial Mount |
|---|---|---|
| How it moves | Up/down & left/right | Along Earth’s axis (one main axis for tracking) |
| Setup time | Seconds — just point | Longer — leveling & polar alignment |
| Ease for beginners | Very easy | Moderate learning curve |
| Tracking objects | Manual, adjust two knobs | Smooth, one axis (or motor) |
| Astrophotography | Limited (short exposures only) | Excellent (long exposures) |
| Weight & portability | Lighter, more portable | Heavier (counterweights) |
| Best for | Casual viewing, Moon & planets, grab-and-go | Serious tracking, deep-sky, imaging |
What is a GoTo mount, and how is it different?
A GoTo mount is any mount — alt-azimuth or equatorial — with a computerized system and motors that automatically slew to and track thousands of objects. After a short star-alignment, you type a target into a hand controller or app and the mount drives the telescope right to it. GoTo is a feature layered on top of a mount type, not a third category.
For beginners who find it frustrating to locate faint objects by hand, GoTo can be a game-changer. Computerized equatorial mounts like the Explore Scientific iEXOS-100 PMC-Eight Equatorial Mount & Tripod combine automatic finding and precise tracking, which is why they’re popular for both visual astronomy and entry-level imaging. Just remember GoTo needs a power source and still requires an accurate alignment to work well.
Which telescope mount type should a beginner choose?
Match the mount to how you actually plan to observe:
- You want simple, relaxed stargazing. Choose an alt-azimuth mount (or a Dobsonian). You’ll spend more time looking and less time fiddling.
- You mainly view the Moon and planets casually. Alt-az is plenty. High-power tracking by hand is easy for a few minutes at a time.
- You want to learn to track the sky or dabble in photography. Choose a manual equatorial mount to build the skill affordably.
- You’re serious about astrophotography. Choose a motorized/GoTo equatorial mount — steady tracking is non-negotiable for long exposures.
- You get discouraged searching for objects. A GoTo mount (alt-az for visual, equatorial for imaging) does the finding for you.
One rule holds no matter what: buy a mount rated to comfortably carry your telescope’s weight, with margin to spare. An overloaded mount shakes, and a shaky mount steals the fun.

Frequently asked questions
Is an alt-azimuth or equatorial mount better for beginners?
For most beginners, an alt-azimuth mount is better because it’s intuitive, fast to set up, and lightweight. Choose an equatorial mount if your main goals are tracking objects at high power for long stretches or getting into astrophotography.
Do I need an equatorial mount for astrophotography?
For long-exposure deep-sky imaging, yes — a motorized equatorial mount tracks the sky’s motion so stars stay as pinpoints. You can shoot the Moon and bright planets on an alt-az mount with short exposures, but galaxies and nebulae need an EQ mount.
What is the difference between a mount and a tripod?
The tripod is the three-legged stand that provides height and a stable footing. The mount is the head that attaches to the tripod, holds the telescope, and lets you aim and track. Many mounts come bundled with a matching tripod.
Is a GoTo mount worth it for a first telescope?
It can be, if star-hopping frustrates you or your skies are light-polluted and objects are hard to find by eye. Weigh the extra cost, weight, and need for power against the convenience — many beginners are happy learning the sky manually first.
Why does my telescope shake even on a mount?
Usually the mount or tripod is too light for the telescope, the legs aren’t fully tightened, or you’re on soft ground. Choose a mount rated above your telescope’s weight, spread and lock the legs, and let vibrations settle after each touch.
