How to See Mars Through a Telescope: What to Expect
To see Mars through a telescope, wait for it to climb high in a dark sky, point your scope at the brightest orange "star" in that part of the sky, and start at low power before zooming in. Even in a small telescope Mars looks like a tiny, salmon-colored disk rather than a postcard planet — and how much detail you catch depends heavily on the year, because Earth and Mars only line up for a good view about every two years.
Mars is one of the most exciting targets for a beginner because it's a real, rocky world you can actually resolve into a disk. But it's also one of the most misunderstood. Many first-time observers expect the giant, feature-packed Mars they've seen in photos, then feel let down by the small dot they see at the eyepiece. Knowing what to expect — and when to look — makes all the difference.
What does Mars actually look like through a telescope?
Through a typical beginner telescope, Mars appears as a small but distinctly orange or reddish-tan disk. It's noticeably not a point of light like a star, and that alone is a thrill the first time you see it. On a good night with steady air, a 4- to 6-inch telescope can begin to show a bright white polar ice cap and a few darker gray markings on the surface, the largest of which is a triangular feature called Syrtis Major.
What you won't see are canals, cities, or crisp surface photos. Mars is small and far away, so even at its best it stays a modest disk. Patience at the eyepiece is your biggest tool: the longer you look, the more your eye adapts and the more subtle detail emerges during those brief moments when the atmosphere steadies.
When is the best time to see Mars?
Mars is only worth serious telescope time around opposition — the point in its roughly two-year cycle when Earth passes between Mars and the Sun, putting Mars closest to us and visible all night long. Between oppositions, Mars shrinks to a tiny dot that shows little more than color.
Here's the key thing for 2026: Mars is not at opposition this year. It passed behind the Sun (solar conjunction) in early January 2026 and spends most of the year as a small, faint morning-sky object low in the pre-dawn east. It slowly grows through the fall and, by late 2026, becomes a genuinely improving target in the evening sky as it heads toward its next opposition on February 19, 2027.
That 2027 opposition is what to circle on your calendar. One caveat worth knowing: it's an "aphelic" opposition, meaning Mars is near the far part of its orbit, so it will look smaller than the headline-making oppositions of some years. Still, it's by far the best Mars viewing you'll get in this stretch, and the months leading up to it (November 2026 into early 2027) are the time to start watching.
Mars viewing timeline at a glance
| Period | Where to look | What to expect |
|---|---|---|
| Early–mid 2026 | Low in pre-dawn sky (or lost in glare) | Tiny dot; color only |
| Fall 2026 | Rising earlier, higher before dawn | Small orange disk; growing slowly |
| Late 2026 | Evening sky, climbing toward winter | Larger disk; polar cap possible in bigger scopes |
| Feb 19, 2027 (opposition) | Up all night, high overhead | Best views of the cycle — disk, polar cap, dark markings |
How do you find Mars in the sky?
Mars is easy to identify with the naked eye once you know roughly where to look: it glows with a steady, warm orange-red light and doesn't twinkle the way stars do. A free stargazing app on your phone will point you straight to it for your date and location — just hold the phone up to the sky and follow the arrow.
Once you've spotted it, follow these steps:
- Let Mars rise high. The higher a planet climbs above the horizon, the less thick atmosphere you look through, and the steadier the view. Avoid observing it when it's low and shimmering near the horizon.
- Start at low power. Use your longest-focal-length (highest number, like 25mm) eyepiece first to locate and center Mars easily.
- Then increase magnification. Switch to a shorter eyepiece or add a Barlow lens to zoom in. Push the power up only until the image stays sharp — too much magnification just gives you a big, blurry blob.
- Keep looking. Spend several minutes at the eyepiece. Detail on Mars comes and goes with the atmosphere, so the reward goes to the patient.

What telescope do you need to see Mars?
You can see Mars as a colored disk in almost any telescope, but Mars rewards aperture (the width of the main lens or mirror) more than most targets, because surface detail is faint and small. More aperture gathers more light and resolves finer detail, which is exactly what a small, low-contrast planet like Mars needs.
Here's how our beginner-friendly options stack up for planetary viewing:
- Best budget start: The National Geographic SRT70MM 70mm refractor will show Mars as a small orange disk and is a great, affordable way to get started — it even includes a solar filter and astronomy app.
- Great value step up: The National Geographic NT114CF 114mm reflector gathers noticeably more light, giving you a brighter, more detailed disk when Mars is well placed.
- Best for planetary detail: The Explore Scientific 6-inch Tabletop Dobsonian packs 6 inches of aperture into a compact tabletop design — enough to reveal the polar cap and darker surface markings on a steady night.
If you're still choosing your first scope, browse our full range of beginner telescopes to match aperture and budget to what you want to observe. For planets like Mars, aim for at least a 4-inch (100mm) telescope if detail is your goal.
Tips for getting the most out of Mars
A few simple habits dramatically improve what you'll see. Let your telescope cool to the outdoor temperature for 20–30 minutes before observing, so heat waves inside the tube don't blur the view. Observe on nights when the stars are shining steadily rather than twinkling wildly — steady air ("good seeing") matters far more for planets than a perfectly dark sky. And give your eyes at least a few minutes to relax at the eyepiece; averted, patient looking always beats a quick glance.
Frequently asked questions
Can you see Mars with a beginner telescope?
Yes. Any telescope will show Mars as a small orange disk rather than a point of light. To see surface detail like the polar cap, you'll want more aperture (ideally 4 inches / 100mm or more) and Mars near opposition, when it appears largest.
Why does Mars look so small in my telescope?
Mars is a small planet and usually far from Earth, so it always appears as a modest disk. It looks especially tiny in "off" years like 2026 when it's far away. It grows noticeably around opposition — the next one is February 19, 2027.
What magnification do I need to see Mars?
Start low to find it, then increase power gradually. Many observers get their best planetary views somewhere around 100–200x, but only if the atmosphere is steady enough to support it. If the image gets blurry, back off — a smaller, sharp image always beats a big, mushy one.
What color is Mars through a telescope?
Mars looks orange to reddish-tan, thanks to iron oxide (rust) dust covering its surface. That warm color is one of the easiest ways to confirm you've found the right object.
Is 2026 a good year to see Mars?
Not especially — 2026 is an "off" year, with Mars small and mostly a pre-dawn object. The good news is that Mars steadily improves through late 2026 on its way to the February 19, 2027 opposition, so this is the perfect time to get your telescope and practice on Jupiter and Saturn first.
