The 20 mm eyepiece will do well for most purposes with its wider viewing, bright and sharp image resolution, and good power. It provides up to a max useful magnification of 140x but I found pushing it to 168x magnification that the manufacturer states will result in picture degradation. You can also use it to observe deep-sky objects like the Orion Nebula or other galaxies far away from our own. Whether you’re a beginner or an experienced astronomer, this travel telescope is sure to impress.

Celestron Travel Scope 70 DX Portable Telescope with - Celestron

Our team of product advisors know what it’s like to buy astronomy equipment for the first time. There are so many types of telescopes and accessories that the process can be overwhelming enough without having to worry about pushy salespeople trying to make a big commission. As a spotting scope, the Celestron TravelScope 70 works. It would be okay for use at a shooting range or for casual birding. The tripod is stable enough when pointed horizontally, and the optics are sharp enough with the low-power eyepiece for the views to be of some value, and aiming the telescope by sighting down the tube works well enough. This became apparent as I was looking through the scope at bright objects like the moon or at targets with high contrast such as a white poster against the setting sun. While the included 45-degree diagonal provides an upright and correct image view, it is in an all-plastic housing and combining this with a short focal length, you’ll inevitably have false coloring on the fringes of target images, also known as chromatic aberration (CA). I want to like the Celestron TravelScope 70, I really do. I have had fun with it. But I just can’t recommend it to beginners for astronomy. And though I’m not an expert on daytime spotting scopes, I’d probably advise against getting one for that purpose as well. It is a nice optic ruined by poor mechanical design and accessories, and unless you’re willing to spend more time and money replacing its accessories (or if you have them already lying about, as I do), I can not recommend it.If you want a telescope that is small, lightweight, and very easy to use, consider the Orion SkyScanner 100 or Zhumell Z100, a 4” tabletop reflector. And at this price point, if you want to scan wide fields of view across the sky searching for bright deep-sky-objects and star fields, consider a pair of binoculars instead. A 10x50mm or 7x50mm pair of binoculars have the same overall light gathering. Despite its many strengths, it does have a few weak points that may be important to consider before purchasing.

The biggest problem with the accessories, other than the tripod, is the 45-degree erecting prism, which goes between the focuser drawtube and the eyepiece. The body is made of plastic, and it feels cheap. It is both an ergonomic and an optical disaster. The Travelscope 70 comes with 20mm and 10mm Kellner eyepieces, providing 20x and 40x, respectively. The construction of both is largely metal, the field of view is decent and the images reasonably sharp, although not as good as a decent Plossl or wide-field eyepiece. However, the choices in focal lengths were poor on Celestron’s part. The 20mm Kellner provides a little too much power for the scope for low-power sweeping, while the 10mm, though decent in quality, provides too much magnification for the scope’s poor-quality optics. The Tripod So, what you’ll be able to see with the Celestron Travelscope 70 is dependent on a variety of factors such as atmospheric conditions, light pollution levels, and your own personal viewing location. Generally, you can expect to observe bright and clear views of the moon’s craters, planets such as Jupiter and Saturn (including their moons), star clusters, and even some nebulae. By night, Travel Scope 70 DX delivers great views of the planets, the Moon, star clusters and brighter deep sky objects like the Orion Nebula and Andromeda Galaxy. During the day, Travel Scope 70 DX doubles as a spotting scope. Enjoy amazing views of birds, wildlife, boats on the water, migrating whales, and so much more. It features coated glass optics that minimize reflection and increase light transmission, resulting in bright and vivid images.The Celestron CPC 1100 StarBright XLT 2800mm Telescope is one of the best celestron telescopes on the market, due to its massive aperture, heavy-duty tripod, and GPS-connected alignment system. The Celestron NexStar 4 SE Telescope earns second place with its large aperture, automated mount, and easy setup, and its low price earns it the title of “best Celestron telescope for the money.” In third is the Celestron 21035 70mm Travel Scope, which is travel-ready and has a large lens and two eyepieces, plus a bargain price. The Orion FunScope is another option for a bit lower of a price, but without the high-quality optics of the 100mm tabletop telescopes it’s a bit harder for us to recommend. The Celestron NexStar 130SLT Computerized Telescope comes with a very large aperture and good eyepieces. It’s great for photography, though its need for collimation hurts its value. Fifth place belongs to the Celestron 114LCM Computerized Telescope, which has a very large aperture and two eyepieces but suffers from poor power efficiency and a shaky mount. Sixth place is taken by the Celestron 21061 AstroMaster 70AZ Refractor Telescope, which provides a smooth position and easy setup but loses value because of its shaky tripod and smaller size. The Celestron Travelscope 70 has an aperture of 70mm. This is a great size for a travel telescope, as it allows you to see many celestial objects while still being portable and easy to use. What is the magnification of the Celestron Travelscope 70?

After my first half hour using the telescope, I was exhausted trying to work around its awful mount. However, in that time, I was able to observe the Double Cluster in Perseus, the Orion Nebula, and the Andromeda Galaxy, and I was pleased enough by them to not immediately write off the telescope as a failure. The TravelScope 70 has an achromatic lens objective with an aperture of 70mm and a focal length of 400mm. Its lens elements are nicely coated without bright reflections. My impression is that, for the money, this is a pretty great objective lens. It won’t hold up to any 70mm Apochromat, but you get what you pay for. Overall, the Celestron Travelscope 70 is perfect for beginners or anyone who loves traveling and exploring the night sky without compromising on quality.The two real letdowns among the accessories are the finderscope and the prism diagonal. The finderscope is ridiculous. Galileo’s telescope was probably better. These things barely belong in a McDonald’s happy meal toy, let alone a telescope. It is barely sufficient for sighting through it to find targets, but it isn’t usable on its own as a wide-field finderscope. I went out one night to compare my Orion ShortTube 80 (optically identical to the Celestron TravelScope 80’s objective lens) with the TravelScope 70. By my calculation, the difference between the two shouldn’t have been especially noticeable, but it definitely was. The view of Caldwell 64, the Tau Canis Majoris Cluster, was so much dimmer than the view through the ST80 that it required averted vision to suspect there was more than one star, whereas the ST80 showed it with a sparkly halo easily. The ST80 could just barely do the two bright components in the Leo Triplet, while I couldn’t see them at all in the TravelScope 70. The overall character of the images was the same (to be expected when observing at the same magnification), but the TS70 was dimmer than it should have been, which confirms that the effective aperture was stopped down. Zane Landers, Thank you so much for taking the time to review this piece of Crap Celestron telescope, your review is 100% Accurate & very true about the Junk telescope Celestron model # 21035 Travel scope. I got my on Aeroplan Miles and is a Piece of Pure JunK, exactly as you describe it. I always been fascinated with the distance stars and Planets and also terrestrial observations. Which telescope for Looking at Moons,Stars and planets,Terrestrial Observations and a good pair of Binoculars for Bird Watching would you recomend? Thanks Reply The Celestron 21061 AstroMaster 70AZ Refractor Telescope is positioned as an entry-level telescope, but there are some reasons that beginners could be better served by a different scope. This one does come with an alt-azimuth mount, which is better than expected on a telescope at this price point. That makes it easy to align this telescope and keep it aligned with objects in the night sky. It also has a reputation for being very easy to assemble, and it’s not a reflector telescope, so you’ll never have to collimate it. Plus, it comes with 45x and 90x magnification due to its great included eyepieces. Secondly, the included diagonal that comes with the scope is of lower quality than what one might expect from a travel scope in this price range. While it’s serviceable and will allow you to view objects right-side-up (which is important for terrestrial viewing), it may introduce some image distortion or reduce overall image brightness.
