Wondering how to align a telescope mount? If you’ve got an equatorial mount, you’ll need to align it with the Earth’s axis of rotation before it can track objects properly. This is called polar alignment, and it’s the step that makes most beginners consider returning their telescope and taking up pottery instead.
It’s not as bad as it sounds. Here’s how to do it without losing your mind.
Why Polar Alignment Matters
The Earth rotates on its axis, which means the stars appear to drift slowly across the sky. An equatorial mount is designed to counteract this drift by rotating around an axis that’s parallel to Earth’s. If the mount’s axis points at the celestial pole (very close to Polaris, the North Star), then turning one knob smoothly tracks any object across the sky.
If the alignment is off, objects will still drift out of your field of view even when you’re tracking. For visual observing, a rough alignment is usually good enough. For astrophotography, you need it to be more precise — but that’s a problem for future you.
How to Align a Telescope Mount: The Quick Method
Step 1: Set up your tripod on firm, level ground. Extend the legs so the mount head is at a comfortable height.
Step 2: Find Polaris. It’s the moderately bright star at the end of the Little Dipper’s handle. The easiest way to find it: locate the Plough (part of Ursa Major), follow the two “pointer stars” at the end of its bowl upward, and they lead you straight to Polaris. Alternatively, use a stargazing app.
Step 3: Point the mount’s polar axis at Polaris. Most equatorial mounts have a latitude adjustment bolt and an azimuth adjustment. Loosen the latitude bolt and tilt the mount until the polar axis is angled at roughly your latitude (in the UK, that’s approximately 51-56 degrees depending on how far north you are). Then rotate the base left or right until the polar axis is pointing north toward Polaris.
Step 4: Look through the polar scope (if your mount has one — it’s a small scope built into the RA axis). Centre Polaris in it. If you don’t have a polar scope, simply sight along the RA axis like aiming a rifle. Getting Polaris roughly centred is sufficient for visual observing.
Step 5: Tighten everything. Done.
This whole process takes about five minutes once you’ve done it a few times. The first time, budget fifteen minutes and some mild frustration.
How to Tell If Your Alignment Is Good Enough
Point your telescope at any bright star, centre it in the eyepiece at medium magnification, and start tracking with the RA slow-motion control only. If the star stays roughly centred for a few minutes, your alignment is good enough for visual work. If it drifts significantly north or south, your polar alignment needs adjusting.
Alt-Az Mounts: No Alignment Needed
If you have an alt-azimuth mount or a Dobsonian, you can skip all of this. These mounts don’t try to follow the sky’s rotation automatically — you just push the telescope to follow objects manually. It’s less elegant but far simpler, and for visual observing it works perfectly well.
This is one of the reasons I often recommend Dobsonians for beginners — no alignment headaches, more time looking at the sky.
Go-To Mounts
Go-To mounts have built-in computers that can automatically find and track objects. They still need alignment — typically a “star alignment” procedure where you point the telescope at two or three known bright stars and the computer calibrates from there. The handset walks you through this, and it usually takes a few minutes.
Go-To sounds like cheating, and some purists will tell you it is. I think it’s a tool. If it gets you observing more objects and having more fun, it’s doing its job. You can always learn manual star-hopping later.

Common Alignment Problems
Mount feels stiff or jerky: You may have the clutch locks too tight. Loosen them slightly so the axes move smoothly, then lock them at the right tension.
Objects drift despite tracking: Your polar alignment is off. Re-align to Polaris. Even a degree or two of error will cause noticeable drift at high magnification.
You can’t find Polaris: It’s not the brightest star in the sky — it’s moderately bright and sometimes gets lost in light pollution. Use the Plough’s pointer stars or a phone app. Also check that you’re actually facing north. I’ve stood in my garden convinced I was facing north when I was actually facing northeast. A compass helps.
The counterweight keeps swinging: Make sure the counterweight is positioned so the telescope is balanced on both axes. An unbalanced mount is stressful on the gears and annoying to use.
Don’t let alignment anxiety stop you from observing. A rough alignment is far better than staying inside because you’re worried about getting it perfect. Get outside, get approximately right, and refine over time.
Once you know how to align a telescope mount, it becomes second nature. Don’t let the process of learning to align a telescope mount put you off equatorial mounts entirely — the tracking ability is worth the initial learning curve.
