Celestron Travel Scope overview

  • 1Description

The Celestron Travel Scope 70mm f/5.7 AZ Refractor Telescope Kit is designed for portability and ease-of-use for both astronomical and terrestrial use. Its refractor-style optical tube has a respectable aperture that gathers copious amounts of light, and a shorter focal length that produces a moderate magnification potential. A photo-style alt-az pan/tilt head easily mounts the OTA with a simple screw and has a single control handle that allows for smooth movement and locks the altitude in place for hands-free use to minimize vibration. Supporting it all is a photo-style tripod that collapses low enough for tabletop use and extends to full-sized height. The included erecting prism corrects views horizontally and laterally to the Travel Scope can be used as a conventional spotting scope, and it comes with to eyepieces offering 20x and 40x magnifications — although any 1.25" astronomical eyepiece may be used. Everything in this kit — OTA, tripod, head, and accessories — fits inside the included canvas backpack to make it as portable possible.

    Celestron Travel Scope reviews

    Travel Scope 70mm f/5.7 AZ Refractor Telescope Kit is rated 4.2 out of 5 by 35.
    Rated 5 out of 5 by from Great scope to carry around First of all, the tripod is terrible, as expected. An OK tripod will set you back at least as much as this scope, so my expectations were not high on that front. Besides that, everything else about it is great. The form factor is perfect, and can be carried anywhere in any backpack. It provides decent light and at 40x magnification, you can clearly observe the moon, Jupiter and its moons, an barely distinguish Saturn from its rings if the conditions are right. I've purchased a set of eyepieces to extend its capacity. With a 6mm eyepiece and a 2x barlow (133x magnification), the image starts to loose its sharpness. It seems to me like this would be the upper limit for any useful magnification for this scope.

    Rated 4 out of 5 by from Celestron 70mm Refractor Travel telescope The shipment arrived promptly and the shipping box was not damaged. The telescope was properly packaged and all parts were there. It assembled fine. It was sky tested and the optics produce excellent sharp images. On the negative side, the finder telescope is hard to adjust to center a star on the crosshairs. It needs to be mounted in a twin ring mount so the forward end of the finder scope can be moved both vertically and horizontally. Using only one mounting ring does not allow vertical and horizontal movement to be able to center a star on the crosshairs. Secondly, the tripod is a bit flimsy and could be more sturdy and solid.

    Rated 4 out of 5 by from Small price, large potential I purchased the 70mm TravelScope with an open mind, hoping to get a low cost, portable spotting scope that might be elevated to the next level of performance with a few tweaks. That is precisely what I got. The Travelscope arrived promply and was packaged very well. I assembled the basic scope and put in the 20x (20mm) eyepiece for a quick view- not bad. Sharpness and contrast was good, not phenomenal but certainly acceptable. Next came the 40x (10mm) eyepiece which showed a noticeable decrease in image sharpness and contrast. Being very familiar with optical testing and adjustments, I rebaffled the scopes interior and carefully realigned its optics (which turned out to be of excellent quality). Now I have a scope that performs very well at powers from 12x-80x.

    Rated 2 out of 5 by from Lousy tripod with descent optics This will be two reviews in one. I bought this as a super budget astro-imaging scope to be piggyback mounted on a Celestron 8 and Advanced VX equatorial mount. I image with a Meade Deep Sky Imager and use Travel Scope 70 (TS70) to image wide field nebulae and star clusters. Checking with a Cheshire eyepiece collimation was a little off. Following suggestions on a website titled Revenge of the Celestron Travel Scope I loosed the objective retainer ring, shook it a little, and that was enough to achieve perfect collimation. First night out with very poor seeing and approximate alignment I was able to get a descent image of the Orion Nebula area. On a different night with better seeing, with an IR blocking filter and excellent alignment I was able to acquire several open clusters. Even with the crude rack and pinion focuser stars were quite sharp. Images of M42 and M37 are attached. So why only two stars? Well mated with a Meade DSI on a descent mount the TS70 delivers descent wide field images making it a pretty good budget imaging scope. However, the scope is sold as a travel scope package with a flimsy, useless tripod. Adding insult to injury one of the locking screws failed after a week. As a travel scope the TS70 will discourage almost any newbie from pursuing astronomy.

    Rated 5 out of 5 by from nifty little scope The temptation for this review is to give the product less than 5 stars but I am resisting that temptation. The reason is that the cost is so small that you have to concede that you got more than what you paid for. I set the scope up for my 5 year old niece at her height and put the full moon in the 20mm eyepiece and she was thrilled. There you have it, it was worth every penny. I use the scope without the diagonal (which is for terrestrial viewing) as a nice finder/guide scope for my refractor. It makes a nice finder with a 32mm plossl or it actually will guide in good seeing conditions using my nexguide autoguider. The extras are a nice bonus: backpack, 45 degree diagonal, 20mm and 9mm eyepieces. I highly recommend the scope for its versatility and for the minimum cost.

    Rated 4 out of 5 by from Good optics, unstable mounting This small 70mm refractor is great for what you pay for it. The included 45 degree diagonal and eyepieces are acceptable for terrestrial viewing. The finder scope is not easy to see through at night. The included carrying bag is nifty, but the tripod is cheap and unstable. Trying to center anything in the eyepiece is next to impossible if you're looking for objects in the night sky. Speaking of, don't expect impressive views of anything except for the moon. Even Jupiter is somewhat disappointing, particularly if you've seen it through a more expensive telescope. Globular clusters can be made out in non-light-polluted skies if seeing conditions are good. Probably the best uses for this telescope are as follows: child's first telescope, guide scope, daytime terrestrial viewing. If you're an adult looking for an inexpensive astronomy scope, spend a bit more on a newtonian reflector on an EQ mount.

    Rated 5 out of 5 by from Nice Little Scope for Travel I take this scope with me when I travel. Tripod is not great but I expected as much for the price. I planned to use this scope on my camera tripod anyway. Scope is nice.
    Date published: 2010-07-16
    Rated 3 out of 5 by from Ok for the price Considering the price and the fact that in addition to the telescope you get a rucksac and a tripod its good value. However, as for what you can see - its a terrestrial telescope primarily. You won't see much of space. The moon can be seen quite well but I get a better view of the moon on my FZ1000 on zoom. It's an ok purchase but not fantastic for astro.
