Owners of Celestron’s PowerSeeker 127EQ telescope love the ability to fine-tune the scope’s R.A. and declination. If you need to replace those adjustment cables, you can do that easily yourself with the Celestron Declination & Right Ascension Plastic Slow Motion Cables for PowerSeeker 127EQ Telescope. 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 comes with two eyepieces, a 10mm and a 20mm, which provide magnifications of 40x and 20x respectively. With these eyepieces, you can see jupiter, saturn, and even some planets. What is the focal length of the Celestron Travelscope 70? The Celestron CPC 1100 StarBright XLT 2800mm Telescope is absolutely the best Celestron telescope in the fleet. It has a massive, 11-inch aperture, which is more than enough to make even the dimmest celestial objects visible, even in areas full of serious light pollution. It also includes a 9×50 finderscope, which is as powerful on its own as some full telescopes. There’s a heavy-duty tripod, which greatly reduces vibrations and makes it easy to align this telescope with objects in the nighttime sky. 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.
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. 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. Smartphone Photography Accessories - Capture images and video through your Travel Scope with the included smartphone adapter and Bluetooth shutter release Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it. As I write this, there are no planets worth looking at (Mars is a dot in even the largest telescopes), so the only high-resolution tests I could put the telescope through were of double stars and the Moon.

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. 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.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. This refractor telescope is equipped with premium-quality optical components that provide clear and crisp images of celestial objects. 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.

There are a few problems with the mechanical design of the TS70. First of all, the (non-collimatable) lens cell, which is similar in design to the ShortTube 80’s and some other cheap achromats I’ve seen, was tightened extremely tight. I put in a lot of elbow grease to loosen the lens cell. The trouble is that this tightened lens cell actually bends the glass, creating “pinched optics.” You might not think glass can bend, but you’re only allowed to bend by 1/1000th the width of saran wrap, so screwing the lens cell down so tight makes the image noticeably fuzzier at high powers. In fact, I’d go so far as to say that the image at first was a mess. After loosening the lens cell just enough that I could hear a slight rattle when shaken (but not too much so that the scope would never be collimated), the image was much cleaner and sharper. Accessories include: two eyepieces (20mm and 10mm), 45° erect image diagonal, and 5x24 finderscope. As a daytime spotting scope, it has a lot of benefits. Using the diagonal is comfortable to use for most terrestrial needs. One area in which I found it provides better than average performance is resolving bullet holes and arrow impacts at the range.
Celestron may be a name you know in the field of astronomy, and the reason is simple. They make good telescopes. If you’re looking to up your astronomy or nature-viewing game, then a Celestron telescope may be an option worth looking into. 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 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.
