Celestron Travel Scope 50 Review – Not Recommended

The TravelScope 50 is an embarrassingly bad telescope that is little more than a decoration or toy.

Celestron offers two low-cost travel scope packages, the Travel Scope 50 and the Travel scope 70. This review will be about the 50mm model.

On the surface, this looks like a great package. It includes a 50 mm refractor telescope with a focal length of 360 mm. Also included are 2 eyepieces, a 3X Barlow lens, a 45-degree erect image diagonal, a 5×24 finder scope, a tripod, and a nice little backpack to keep it all ready to grab and go. Sounds great, but read on.

Bottom Line
Not Recommended Telescope

We can’t recommend this package as more than a child’s toy. Every corner has been cut and the results are a scope that disappoints in every way. There are better options available at similar prices.

The Optical Tube

The Celestron TravelScope 50 is a 50mm f/7.22 achromat. At this size and focal ratio, there should be fairly little chromatic aberration. The aperture, while tiny, is sufficient to show you details of the Moon, planets, and the brightest deep-sky targets. Unfortunately, for whatever reason, there is poorly designed internal baffling, which is usually there to control light scatter and internal reflections. This actually stops the telescope down to 20mm, making it essentially unable to deliver an image much better than the naked eye – your eye dilates to around 7-8mm under good conditions. With only 20mm of aperture available, the telescope becomes an f/18 and provides ridiculously dim images of even the Moon. You are using a telescope that is about on par with what Galileo had

Celestron Travel Scope 50

The TravelScope 50 also has a 0.965” plastic rack-and-pinion focuser, so using a quality diagonal besides the provided one is going to be tricky if not costly and impractical. The entire tube, focuser, and lens cell are plastic, making for a ridiculously lightweight instrument – only around 300 grams (less than ½ a pound).

Accessories

The TravelScope 50 includes two Huygenian eyepieces, 1.25” units with focal lengths of 20mm and 8mm, providing 18x and 45x, respectively. These are extremely bad eyepieces made almost entirely out of plastic (including the lens), and they provide fuzzy views that require jamming your eyeball into them to even see. They also have narrow apparent fields of view, and the resulting effect feels like staring down a soda straw. 

For a star diagonal, the TravelScope 50 includes a 45-degree erecting prism that adapts the focuser to fit 1.25” eyepieces and flips images to be correct left-right. It’s of quite low quality, and the 45-degree angle makes it less-than-ideal for pointing the scope high in the sky.

For a finderscope, Celestron includes the same 5×24 finder supplied with many of their low-quality entry-level scopes, like the PowerSeekers. Not only is this finder nearly impossible to align with the main telescope, but it also provides extremely dim and fuzzy images thanks to its single-element plastic objective lens. It’s also, thankfully, completely unnecessary with the TravelScope 50, which itself is only a little bigger than some finderscopes and can easily be aimed by sighting along the tube with a low-power eyepiece in the focuser.

The included backpack is of low quality but functional. Everything fits nicely inside. 

The Tripod

The tripod included with the TravelScope 50 is pretty low quality; basically, it’s just a cheap camera tripod like the kind you can order on Amazon for around $10. The good news is that the TravelScope 50 is so absurdly small and lightweight that it basically does not matter. For once, Celestron has managed to supply a mount adequate for the scope it’s sold with, though the TravelScope 50 is so bad that this essentially doesn’t matter.

Alternative Recommendations

While the TravelScope 50 is at a price where it’s arguably quite hard to find a good telescope, there are a few options to consider.

  • The Zhumell Z100 and Orion SkyScanner provide double the advertised aperture (and 5 times the real aperture) of the TravelScope 50, with rock-solid mounts, sharp views and good quality included eyepieces.
  • For a bit less money, the Orion FunScope is an option, and while it comes with good eyepieces and an easy-to-use mount its optics are far from high quality.

What can you see with the Celestron TravelScope 50?

As a daytime spotting scope, the TravelScope 50 produces a fairly dim image with a cloudy edge around the field of view using the included H20 mm eyepiece, which provides 18X. As long as you are not too fussy about color and clarity, this arrangement is at least usable in bright sunlight. The central 50% of the image can be brought into fairly sharp focus.

When fitted with the 8 mm eyepiece, 45X, the image is just awful. It is dark, difficult to focus, and has significant color aberration, even in bright sunlight. We consider this eyepiece unusable for spotting scope service. So, as a spotting scope, we would give it 2 out of 5 stars based on the package, but the optics are not great and the included eyepieces are very low quality.

As an astronomical telescope, this package fails in so many ways. I give it 1 star out of 5 as an astronomical telescope. The 45-degree correct image diagonal does not work well for astronomy in this or in any scope. To view a target that is more than 40 degrees above the horizon, you have to get into a very awkward position. You could buy a 90-degree star diagonal, but we would not recommend investing in that with this scope. With the included eyepieces, you could view the Moon, but typically bright star clusters are very dim and the image is not clean anywhere outside of the center 50% of the field of view with the included eyepieces. 

Pricing and Availability

When this Celestron TravelScope 50 review was first published in March 2019, the scope cost roughly $50. Since then, there has been small price inflation due to covid. For the accurate up-to-date pricing, visit HighPointScientific (*not an affiliate link).

  1. A huge disappointment this item. My sons bought it for me as a present, thinking I would derive hours of enjoyment. I am very resentful that Celestron wasted their money and took advantage of their kind thought by trapping them as novices into this purchase. The scope is UTTERLY useless as an astronomical scope which Celestron’s marketing and additional software disc suggest it is good for. The only thing you can look at in the night sky with this is the moon, and frankly, a pair of 10×50 binoulars of mediocre quality would be far far easier to use and better. This item ought to be immediately withdrawn from sale if Clestron have any desire at all to be a decent company. I doubt they do have any such commitment, since they must know full well, how useless the scope is.

  2. I see that your experience agrees with mine when it comes to this scope. I consider it more of a child’s toy than any sort of serious or useful spotting or astronomical scope. I would not recommend it to anyone.

    The gift was given out of love and affection. If you can’t return it then use it the best you can. If you want a better scope, there are some decent starter scope for about $200. You can read about some recommendations here. Get up to about $400 and they start getting pretty good.

    As in most things you buy, you get what you pay for, but in this case, the Travel Scope 50, I don’t think you do.
