Celestron 21035 Travel Scope 70 Portable Refractor Telescope Kit with Backpack, Black, 70mm

Product Information

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.

The Celestron 114LCM Computerized Telescope is a good telescope but has some peripheral issues that cost it a few positions on our list. On the plus side, it’s computerized like a lot of the top-performing models. If you haven’t learned how to find stars, nebulas, and other planets in our solar system, this telescope can guide you to them once it’s been aligned. It has a very large 114-millimeter aperture, so you can get great detail that smaller telescopes just can’t match. Plus, it comes with two eyepieces, so you’ll be able to see celestial objects at 60x and 167x magnification right out of the box. The included finder is a plastic 5×24. These 5x24s have a singlet(!) plastic objective lens, an aperture stop to control the resulting aberrations that make the image unusably dim, and an eyepiece with a drinking-straw-like field of view. It is less effective than those toy pirate telescopes made for little kids. Not only is the finder useless, but it’s also completely pointless, as the scope’s wide field at low power means it doesn’t really even need a finder. It basically acts as its own finder. The Celestron ExploraScope 22103 114AZ Reflector Telescope is priced like a beginner’s telescope, but it has some shortcomings that make it a poor choice except for those who really want to learn. On the plus side, it has a stable mount and tripod, so you won’t have to worry as much about that part interfering with your operation. There’s a 114-millimeter aperture, which is fairly large for the price. The included 2x Barlow lens is a nice touch, increasing what you can do with this telescope and its eyepieces without driving the price up too much.

Overall, the stability and versatility offered by the Celestron TravelScope 70 tripod make it an excellent choice for those who want a reliable telescope for both terrestrial and astronomical observations.

I was able to see the Clown Face Nebula, though it required a higher magnification of 67x to resolve it as a planet-shaped nebula instead of a star, I only suspected it was a nebula at 40x. Firstly, its compact design makes it perfect for travel or outdoor adventures. Additionally, the telescope comes with an adjustable tripod that provides a sturdy base for your observations. If you go in with the correct expectations (objects will be dim and gray) and look for the right objects (look for objects in guides for small telescopes and binoculars, rather than the famously named nebula you’ve seen in pictures), the telescope can work just fine for deep sky viewing from a suburban or darker sky. In a rural sky, it’d be powerful enough to see every one of the Messier objects. I find that it’s much easier to find and appreciate deep sky objects in a small scope after you’ve gotten familiar with deep sky observing in a larger telescope. But there’s no reason you can’t start small if you set your expectations right. 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 The two eyepieces are a 20mm and a 10mm Modified Achromat (a variant of a Kellner eyepiece that has three elements). They have fairly wide fields of view, sharp centers, and passable edges. They’re nothing special, but they’re far better than what many beginner telescopes come with, and they definitely work for this purpose.

After a rest indoors, I set the telescope up again with my good tripod, the mirror diagonal off my Orion ST80, and a red dot finder, and I went out and had a lot of fun with it. It isn’t a powerful telescope, but I personally enjoy small telescope observing quite a lot. The wide-field views you can get with small short telescopes make up for the small aperture, so you can fit a lot of stars in the eyepiece. 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. Reflecting telescopes are more fragile because the mirrors are not fixed in place inside the tube. They occasionally need collimation. Meaning, the lenses need to be adjusted for optimal alignment and cleaning. For this reason, reflecting telescopes are often considered the best home telescope, as they do not need to be moved. Firstly, the scope is a refractor type which means it can suffer from chromatic aberration, especially when used at higher magnifications. This can result in color fringing around bright objects such as the Moon or planets and may detract from the viewing experience for some astronomers.

The included 45-degree erecting diagonal is not only uncomfortable to use for an astronomical telescope but also extremely low in quality. The entire body and housing is plastic, as is the barrel for inserting it into the focuser drawtube. The prism seems to be plastic too. This telescope features an erecting eyepiece for easier viewing, a 5×24 finder scope located on the side, and a convenient phone adapter that allows you to take videos and pictures. The phone adapter also helps with searching for celestial bodies and can act as a finder. This telescope set weighs only 2.07kg, including the lightweight aluminium alt-az tripod with retractable legs. No tools are required for setup. Despite its many strengths, it does have a few weak points that may be important to consider before purchasing. If you’re looking for a portable and easy-to-use entry-level telescope that is perfect for travel, the Celestron Travelscope 70 might just be what you’re looking for. This 70mm refractor telescope is designed to be lightweight and easy to transport, making it the ideal companion for any astronomer who loves to travel. What is the Celestron Travelscope 70?The Celestron Travelscope 70 has a 70mm aperture which allows for good light-gathering capabilities. The magnification range is from 20x to 165x, depending on the eyepiece used. The focal length of this travel scope is 400 mm which makes it suitable for viewing large objects like planets. The optics in the Celestron Travelscope 70 are of good quality and provide clear images without much distortion. With its compact size and easy portability, this travel scope makes for an excellent choice for beginners or those who want to take their telescope on trips. This refractor telescope features an equatorial mount and a 70mm aperture with a 700mm focal length. It comes with 10mm and 20mm Plossl eyepieces. Plossl eyepieces effectively reduce the halo effect and chromatic aberration, both of which can diminish your viewing overall experience. Plossl eyepieces also create a brighter image so you can get a clear picture of a variety of planets and other celestial objects.
