Product Description

This telescope was designed with traveling in mind while offering exceptional value. The Travel Scope is made of the highest quality materials to ensure stability and durability. All this adds up to a telescope that gives you a lifetime of pleasure with a minimal amount of maintenance. Featuring a compact and portable design with ample optical performance, the Travel Scope is ideal for terrestrial as well as casual astronomical observation.

The Celestron 21035 Travel Scope 70 is a compact 70mm refractor telescope optimized for portability and convenience. The telescope, the tripod, and all the accessories fit conveniently into a padded backpack style soft carrying case. The complete accessory package includes a 45 degree correct image prism, a 20mm eyepiece for 20X magnification, and a 10mm eyepiece for 40X. The fully illustrated instruction manual is supplemented by a copy of "The Sky X" astronomy software that turns your PC into a virtual planetarium.

With a focal length of 400mm and a focal ratio of f/5.7, the Travel Scope 70 compares surprisingly well with popular f/5 "Short Tube 80" refractors but at a much lower cost. The Travel Scope 70 uses a number of plastic components to keep the cost and weight down, including a plastic focuser and plastic lens shade, but the all glass lenses deliver beautiful views of backyard birds during the daytime and lovely views of the Moon and stars at night.

The Travel Scope 70 offers daytime views that compare with more expensive spotting scopes. The 20mm eyepiece gives 20X magnification and a 2.5 degree field of view, with plenty of crisp detail when I’m looking at backyard birds. The travel Scope 70 is also quick and easy to set up at night. The deep orange glow of the recent Lunar Eclipse was simply gorgeous, and I was even able to take some pictures using the Travel Scope 70 and a PowerShot camera. When I look at Jupiter using the 10mm eyepiece (40X magnification) I can easily see four moons near the planet. And rich field views of the Milky Way are often at their best in a small scope with a wide field of view.

The tripod included with the Travel Scope 70 is described as a “full size photo tripod”, but I like it best as a table-top tripod with the legs kept short. The tripod is designed to be light and compact, but that means the legs are thin and wobbly when fully extended. --Jeff Phillips

Amazing telescope. I have used a number of telescopes and this is one of the best based on flexibility, ease of use and performance. When mounted on a simple Eq. tracking mount I am getting better pictures than with my C925 that has been a significant source of disappointment. For this price there is no better telescope in the market.

Just edited my original review to add a few photos I took last winter, including lovely comet Lovejoy. These photos are from a really dark place and were processed with Photoshop. However, I just needed a 1-minute exposure at 6400 ISO with my Canon DSLR connected directly to the rear of the telescope (no diagonal). Then I mounted the telescope on a regular Eq. Mount (an additional advantage of this telescope is that it is very light so no heavy duty mount is required... however it needs to be properly aligned and you need to be careful not to touch the camera, telescope or mount when taking a photo to avoid vibration). When I bought this telescope I was needing the equivalent of a 400mm to 600mm lens for my Canon DSLR. These lenses cost several thousand dollars so I bought instead this telescope as it was a very low risk investment compared to the potential benefits. As you can see it really paid off....

I bought this telescope so that I would have something to look at the sky with when I travel to observatories in the northern and southern hemispheres. For the price this telescope is a pretty good value; it's portable (nicely fits into my suitcase) and reasonably powerful. It's great for looking at star clusters which need a wide field of view to fit the whole thing into view. This was the first telescope I've had where I could fit the entire Pleiades cluster into the field of view. At home, it's a great telescope since it's fast to set up and take outside for a few minutes. You may not think about it, but the amount of work to set up a telescope will translate directly into how much you use it.

The only con that I see with the telescope is that the tripod it comes with is fairly unstable; it's a regular camera tripod. It may be a bit frustrating trying to center on objects since it's a bit wobbly and hard to precisely center on something since it flexes a bit as well. Centering with the higher magnification eyepiece is even more tricky. I found that a different tripod I had for my camera works a bit better. Someone buying this for casual use may not notice, but the image quality does degrade toward the edges of the field of view; that's to be expected since it has such fast optics and wide field of view.

I have to say, I am very impressed. The packaging was perfect, and the delivery was very fast with this product. This made the perfect gift for my 11 yr old son, and he loves the fact that it came with its own travel bag, so that he can take it with him every where he goes. Oh, and I looked at the sky from it as well, and the stars and the moon could not look any more beautiful. I am very happy with this item.

This 70mm refractor has been great fun to use. First, the negative. I give it 4 stars because, as stated in other reviews, the finder scope and the included tripod leave a lot to be desired. I replaced the tripod immediately with a much larger, sturdier tripod with a quick-release. The spotting scope needs to be adjusted constantly; I find it difficult to focus and honestly not much use around any amount of light pollution.

Now, the positive: I don't have much trouble finding bright stars by dead reckoning and then hopping from there. I've found the Moon, Jupiter and Saturn with no trouble at all, and what we see there is fantastic! Jupiter's moons and Saturn's rings are beautifully distinct. Mizar A & B and Alcor are easily distinguishable, along with stars down to 10th or 11th magnitude.

I also love bird-watching, and the upright image diagonal gives great views of the local avians with a pretty decent near-focus (5.8m) for that purpose.

The scope is very light (1.5kg) but seems quite well put together, and assembling it for use is easy and quick. In fact, we realized that it's light and compact enough to fit into a camping backpack, which hopefully means we'll get a LOT of mileage out of it in exotic places.

The eyepieces, as someone else mentioned, are standard 1.25" size also used by the much larger scopes I've had my eye on, meaning I'm not afraid to invest in high-quality upgrades.

They say the best scope is the one you use most. This scope puts up absolutely no barriers to taking it out to starwatch as much as possible. I was a little hesitant to buy it, but now I really wish I'd bought it a much sooner. Great value for a great price.

I'm in Afghanistan, we decided to get a telescope for looking at the stars and planets out here since there's much less light pollution in western Afghanistan than there is anywhere in the US. At $60 with free shipping the price was right, and it only took a week and a half to get out here. Setup was easy, and right away I was able to look at Jupiter and see four of its moons. Then I looked at our moon and saw crisply defined craters. Haven't looked at much else yet. The tripod, as noted by others, is a little buggy. But the price is right, and you can get a better tripod pretty cheaply. I probably won't bother, we have enough stuff out here that I can put the tripod on top of that I don't really need to extend the tripod legs fully.
