The Celestron Travel Scope 80 is an 80mm refractor that packs into a backpack and weighs about 4.5 lb with the tripod. I tested mine in spring 2023 for the first version of this review and it is still the scope I pick when I need to carry everything in one hand. This update covers setup, what it shows of the Moon, planets and deep sky, where the build cuts corners and which telescope to buy instead if portability is not your first concern.
The short version: it is a good small scope for the Moon, the planets and daytime scenery. It is a poor choice for faint galaxies and nebulae. If that matches what you want to look at, it is hard to beat for how little it weighs.
Verdict
4.4 out of 5 as a travel and kids’ telescope
Buy the Travel Scope 80 if you want a telescope that goes in a backpack, sets up without tools and shows the Moon craters, Jupiter’s moons and Saturn’s rings. It is a fine first scope for a child and a sensible second scope for an adult who already owns a bigger one. Skip it as your only backyard telescope if you plan to chase faint objects. A larger aperture does more for the view than any accessory, and the tripod is the weak part of the kit.
Still sold: yes. Amazon US lists it new, shipped and sold by Amazon (checked November 2, 2026).

Is the Travel Scope 80 still available?
Yes. As of November 2026 the Travel Scope 80 is in stock on Amazon US and sold directly by Amazon, with a 4.2-star average from more than 1,800 ratings. It has not been replaced. The 70mm model in the line is now the Travel Scope 70 DX, covered below. Stock moves, so use the button above for the current status. If it shows as unavailable, the 70 DX is the closest substitute.
Setup and portability
Assembly takes a few minutes and needs no tools. The tripod legs extend to full height, the tube clamps to the mount, the diagonal and an eyepiece go into the focuser and the finderscope slides into its bracket. A child can do most of it. I still supervise the first setup, mostly so nobody drops the eyepieces.
The whole kit fits in the included padded backpack, and that is the reason to buy this scope. I have set it up on a balcony rail and on a flat wall top without any planning. The tube is about 18 inches long, so it also fits in a carry-on bag.
Do two things before the first night. Align the 5×24 finderscope on a distant object in daylight, such as an antenna or a chimney. It takes two minutes and it makes finding the Moon easy. Then check the finder again after you pack and unpack the scope, because the bracket can shift.
What it shows
With the supplied eyepieces the power is 20x and 40x. Add a 2x Barlow and you get 40x and 80x. That is enough for everything below.
The Moon
The Moon is the best target for this scope. At 20x the whole disk fits in the field. At 40x the terminator, the line between light and shadow, shows crater walls, central peaks and the dark maria. Around full Moon the glare tires the eye, and a Moon filter fixes that.
Planets
- Jupiter: two dark cloud belts and four moons in a line at 40x. The belts sharpen at 80x with a Barlow.
- Saturn: the rings are clear at 40x as a tilted oval around a small disk. The gap in the rings, the Cassini Division, needs higher power and steadier air than this scope gives me.
- Venus: a crescent or half disk depending on the month. It is bright enough to look overexposed.
- Mars: a small orange disk. Surface markings appear only for a few weeks around opposition, which comes every two years.
- Uranus and Neptune: pale dots. You can find them with a chart, but no telescope this size shows detail on them.
The 80mm f/5 lens is an achromat, and at this focal ratio it shows false color. On the Moon’s bright limb, on Venus and on Jupiter I see a violet-blue edge. It does not ruin the view and a few minutes in you stop noticing it, but it is the main optical trade for the low weight. A slower scope such as the StarSense LT 80AZ below shows much less of it.
Deep sky
An 80mm lens gathers enough light for the brightest objects and no more. The Orion Nebula shows as a gray fan with its four Trapezium stars at 40x. The Pleiades nearly fill the 20x field. The Double Cluster in Perseus is a good target at 20x. The Andromeda Galaxy is a faint oval smudge with no spiral structure, and it only shows from a dark site. The globular cluster M13 is a small fuzzy ball with no separate stars. Faint galaxies and nebulae need more aperture, and my aperture guide explains why. For a realistic preview, see the photos in my 70mm telescope guide, since an 80mm shows a little more of the same.
Daytime
The Travel Scope works as a spotting scope. Celestron lists wildlife and distant scenery among its uses, and at 20x a hillside or a bird on a wire is bright and sharp. This is why it suits camping and hiking trips.

What annoys me
- The tripod. It is steady on a flat floor or a wall top. On soft ground or a sloped patio it wobbles, and a touch on the focuser leaves the image shaking for a moment. I keep power at 40x or below on uneven ground.
- Plastic threads and fittings. Nothing has failed on mine, but the focuser and several connections are plastic. I do not expect them to take years of rough use as well as metal would.
- The backpack. The material feels thin. It carries the kit, but it is the first part I would expect to wear out.
- False color. A fast achromat shows violet edges on bright objects. See the planets section above.
- The finderscope bracket. It shifts after packing, so check the alignment each time.
- The eyepieces. The 20mm and 10mm Kellners work and I would not replace them first. The 10mm has short eye relief, so keep your eye close.

Travel Scope 80 compared with the alternatives
The right alternative depends on what you give up. The 70 DX saves weight and money. The StarSense LT 80AZ keeps the 80mm lens and adds an app. The Heritage 130P trades portability for a much larger mirror. If you are still choosing, my travel telescope guide and the telescope finder narrow the field.

Lighter and cheaper
Celestron Travel Scope 70 DX
The 70 DX keeps the same 400mm focal length and the same 20mm and 10mm eyepieces. The 80mm lens gathers about 30 percent more light, which shows in the Moon and in brighter deep sky objects, and the 70 DX is the lighter kit at about 3.3 lb. The listing includes more in the box: a 2x Barlow, a Moon filter and a Bluetooth shutter remote for the phone adapter. I have not used the 70 DX, so I am going by the listing. If the extras matter more to you than the extra lens, it is the better value.
- Optics: 70mm achromatic refractor, 400mm focal length
- Choose it over the Travel Scope 80 if: weight and the included extras matter more than the larger lens
App-guided
Celestron StarSense Explorer LT 80AZ
The lens is the same 80mm size, so the light grasp is the same. The differences are a 900mm focal length, which cuts the false color. The other is a phone dock with an app that tells you where to point. The cost is weight and length: the kit is about 9.2 lb with a tube near 38 inches, so it rides in a car trunk and not a backpack. I own this one too and cover it in my LT 80AZ review.
- Optics: 80mm achromatic refractor, 900mm focal length
- Choose it over the Travel Scope 80 if: finding objects is the problem and you can carry more
More aperture
Sky-Watcher Heritage 130P
This tabletop Dobsonian has a 130mm mirror, which collects about 2.6 times the light of the Travel Scope 80. Galaxies, nebulae and star clusters show far more. It has no false color because it is a reflector. It weighs roughly three times as much as the Travel Scope, it needs a sturdy table or stool and its mirror needs a short cool-down outside. It collapses for transport but it is a car scope, not a backpack scope. I have not used it, so I am going by the listing and its ratings.
- Optics: 130mm Newtonian reflector, 650mm focal length
- Choose it over the Travel Scope 80 if: you want the best views and can carry a heavier scope
More tabletop options are in my tabletop telescope guide.
What I would add
The scope is usable out of the box. These three additions are worth buying.
More power
Celestron Omni 2x Barlow
A Barlow doubles the power of each eyepiece: 40x with the 20mm and 80x with the 10mm. The 80x view of Saturn and Jupiter is the best this scope gives without buying a new eyepiece. I wrote a full Omni 2x Barlow review, and the Barlow lens guide lists other options.
For the Moon
Celestron Moon Filter
It threads into the bottom of the 1.25″ eyepieces that come with the scope and cuts the glare from a bright Moon, so the surface detail is comfortable to look at. It also takes the edge off Venus. I use one on any night the Moon is more than half lit.
Night vision
Celestron Red LED Headlamp
Red light protects your night vision while you swap eyepieces and read a chart. On a camping trip with a backpack scope it is the one accessory that weighs almost nothing and gets used every night.
For general advice on eyepieces, see Plössl vs Kellner eyepieces and the magnification calculator.
Specs explained
Aperture is the diameter of the main lens. More aperture collects more light and shows finer detail.
Focal length is the distance from the main lens to the point where it focuses the image. Magnification is the telescope’s focal length divided by the eyepiece’s focal length, so 400mm with a 10mm eyepiece gives 40x.
Focal ratio is focal length divided by aperture. At f/5 the Travel Scope is “fast”: it gives wide fields and shows more false color than a slower scope.
Maximum magnification is the most power the optics can use before the image only gets bigger and blurrier. A common rule is twice the aperture in millimeters, so about 160x for this scope. The 189x on the box is a theoretical figure.
Limiting magnitude is the faintest star the telescope can show. A higher number means fainter. Celestron quotes 12 for this scope under ideal skies, and city skies cut that sharply.
Final word
The Travel Scope 80 does what it was built for. It goes anywhere, it sets up in minutes and it shows the Moon and planets clearly. Its limits are the small aperture, the false color of a fast achromat and a tripod that wants flat ground. If you accept those, it is an easy recommendation as a travel scope or a first telescope for a child. If you want the best view for your money and can carry more, look at the Heritage 130P. If you want help finding objects, take the LT 80AZ.

FAQ
Is the Celestron Travel Scope 80 still available?
Yes. As of November 2026 Amazon US lists it new and sells it directly. If it is out of stock when you look, the Travel Scope 70 DX is the closest alternative.
Is the Travel Scope 80 good for beginners?
Yes. It sets up without tools, needs no collimation and gives clear views of the Moon and planets on the first night. It does not find objects for you, so a beginner needs a finderscope alignment and a star chart or app. The StarSense LT 80AZ is the easier choice if finding objects is the worry.
What can you see with the Travel Scope 80?
The Moon’s craters and mountains, Jupiter’s belts and four moons, Saturn’s rings, the phases of Venus, the Orion Nebula, the Pleiades, the Double Cluster and the core of the Andromeda Galaxy from a dark site. Faint galaxies and nebulae look dim in an 80mm lens.
How much magnification does the Travel Scope 80 have?
The supplied 20mm and 10mm eyepieces give 20x and 40x. A 2x Barlow doubles that to 40x and 80x. Celestron lists a maximum of 189x, but the useful limit for an 80mm lens is about 160x, and the image gets soft before that.
Can you see Saturn’s rings with the Travel Scope 80?
Yes. At 40x the rings show as a tilted oval around the planet. At 80x with a Barlow they are clearer. The Cassini Division, the gap in the rings, needs steadier air and more power.
Can I use the Travel Scope 80 during the day?
Yes. Celestron lists wildlife and distant scenery as uses. Never point any telescope at the Sun without a solar filter made for it, since sunlight can cause permanent eye damage.
Travel Scope 80 or Travel Scope 70 DX: which should I buy?
Buy the 80 for the larger lens, which gathers about 30 percent more light. Buy the 70 DX if you want the lighter kit and the extras in its box, which include a 2x Barlow and a Moon filter.
Can I take the Travel Scope 80 on a plane?
The tube is about 18 inches long and the kit weighs about 4.5 lb, so it fits in a carry-on bag. The backpack it ships in is made for carrying it. Check your airline’s size limit for the bag you choose.
Can I take photos with the Travel Scope 80?
You can take phone photos of the Moon with the included smartphone adapter. Planets come out small, and the scope does not track, so long exposures of deep sky objects are not possible.
