The Good
The Bad



Getting your first telescope can be a challenging task, which is why we are going to give you several pieces of advice that you can rely on in the future, whenever you intend to upgrade or replace your chosen device. We’ll tackle some of the critical factors you have to consider in our comprehensive buyer’s guide. Check it out below.


Choosing a type

There are three typical kinds of telescopes that are available on the market today. Some are refractors, others are reflectors, and the last and possibly, the most powerful alternatives, are catadioptric telescopes. If you’re looking for a reasonable 70mm choice, chances are that you’d benefit from considering refractors as the aperture they usually come with ranges from 50 to 150mm.

Reflector telescopes traditionally have an aperture of 114mm to 400mm. Catadioptric alternatives are thought of as hybrids as they often combine the attributes of reflectors and refractors, but they ensure superb optical performance. These models have apertures ranging from 90mm to 400mm.

The lower the aperture of the device, the less likely it is to cost a pretty penny. The best 70mm refractor telescope is a good choice for beginners, but it might fail to satisfy users who have already learned the basics of using such a device or who have become accustomed to the celestial objects they can observe. Because of this aperture, you will have no means of seeing deep-sky objects, galaxies, or nebulae as this kind of telescope will fail to provide a clear picture of such subjects.


Mounting system

Most of the models we have come across come with mounts of their own, which means that you won’t have to purchase one separately. This is a beneficial aspect of giving some thought to as you won’t be forced to spend more money or be bothered by an extensive research that you might have to perform to make sure that the mount is entirely compatible with your telescope.

Mounts can be of two types. The altazimuth design is quite common nowadays as it enables owners to perform both horizontal and vertical movements. The altazimuth of some cutting-edge models is computerized and maybe even features a GPS system, which ca both mean the world to a complete beginner.

German Equatorial mounts can be found in some models, but they need a bit more care as they have to be aligned perfectly. As with their altazimuth counterparts, such mounts can be computerized or motorized.

Focal length

It goes without saying that, if you ended up here, you’ve already decided on the aperture that you want your telescope to come with, which is why this will not be a topic that we are going to tackle. The focal length and the magnification of the eyepieces, however, need to be addressed so that you know what to expect from the unit.

Typically, most people tend to think that longer focal lengths are always better, but that is not always the case. A shorter one might be an excellent choice if what you intend to do is look at large patches of the night sky. A mid focal length provides clear images of certain celestial bodies such as planets and the moon. Telescopes with long focal lengths are necessary if a greater magnification is what you are focused on, so you can have a chance at seeing deep-sky objects, galaxies, and nebulae.

The aperture is by far the most important factor to bear in mind, and if you can’t afford to purchase any telescope that comes with a great aperture than 70mm, you’ll have to be aware of its limitations.

To make it easier for you to settle on one model or the next, we’ve compiled a list of the critically acclaimed choices out there. Based on what we found, these units have gathered some of the best 70mm telescopes reviews.

The neat thing about this kit is that, in spite of being so budget-friendly, it comes with the tripod, an Orion Moon Map, as well as a set of accessories which all manage to increase the value offered by this alternative.

The core difference between this model and that which we have showcased above consists of the focal length as the Orion 10034 comes with a 400mm one.

If, for example, you like viewing wildlife, doing a bit of birdwatching, or just looking at the scenery nearby your vacation destination, this model is a winner when it comes to versatility.

Available either as a telescope only pack and as an accessory bundle, this Celestron alternative is another unit to consider if you’re looking for something that offers a bit more performance. In that sense, it should be noted that the focal length of this model is 700mm, thus surpassing that of many of its competitors.

What’s more, the Celestron PowerSeeker boasts a 3x Barlow lens which ensures that the magnification can be multiplied without you having to change the eyepiece all the time.

5. Meade Instruments Infinity 70AZ Refractor Telescope Metallic Blue


In many respects, this Meade 70mm telescope somewhat resembles the Celestron PowerSeeker we’ve tackled above. It has the same focal length of 700mm. However, the fact of the matter is that what sets the difference between one and the other is that the Meade model is accompanied by an Altazimuth mount instead of a German Equatorial mount.

The slow motion control rod that the mounting system has been equipped with enables you to track your preferred celestial objects with ease. Both low and high magnification eyepieces are provided in the pack, as is a 2x Barlow lens.

Since this product is one of the most reasonably priced ones we have managed to track down, it might be an excellent option for those looking for a beginner’s telescope that’s worth its weight in gold. The red dot viewfinder even allows you to point the scope at your subjects. Plus, both an instructional DVD and astronomical software can be found in the box, thus enabling you to learn a bit about astronomy before starting to use your first telescope.



This telescope is equipped with an aperture of 70mm that is adequate for the casual observation of celestial objects in the night sky and provides a great way to introduce kids to the science of astronomy.

The rack-and-pinion focuser makes it easy to find the right setting to view the celestial objects with enough clarity and brightness on clear nights.

The altazimuth mount provides a good enough platform for positioning the scope on a less shaky stand compared to just holding the device in the hand, while the slow-motion control rod enables the precise tracking of objects night and day.

Get the exact magnification you want thanks to the supplied low and high magnification eyepieces that accommodate a variety of viewing conditions.

The provided Barlow lens delivers twice more power for the magnification eyepieces for a better clarity or greater amount of detail, as preferred by the user.



This device does not ship with an erect-image diagonal or mirror so viewed images appear upside down when seen through the eyepiece.
