70mm telescopes – Buying guide & Comparison
If you’re short on time and you just want to find the best 70mm telescope, this short paragraph should help you get exactly the model you need. According to our findings, the iOptron 6002 is the best because it can be used both efficiently and easily by beginners and amateur astronomers as it will allow them to have a peek at planets, bright stars, as well as the Moon. The model has been outfitted with an equatorial mount boasting a slow motion control that enables you to discover and track those celestial objects that are of interest to you. The diagonal and eyepiece provided in the box can let you get the most of the product by allowing you to use it both for astronomical and terrestrial observation. If the iOptron 6002 is unavailable, your second option should be the Orion 10034.
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.
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.
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.
Top 70mm telescope reviews in 2017
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.
If you’re in need of a decent beginner’s telescope and haven’t found one that best meets your requirements, perhaps you should consider this iOptron unit. It comes with a 70mm aperture and a focal length of 900mm which both work together in providing excellent images of the Moon, stars, and planets.
The iOptron 6002 is a great choice for people who would like to teach their kids how to use a telescope, in general, although the EQ-2 German equatorial mount might be a bit harder to explain. Nonetheless, since the mounting system has been equipped with a slow-motion control and setting cycles, you won’t have that much trouble discovering and tracking your favorite celestial objects.
One of the other advantages made possible by the design of this product is that it is lightweight and easy to use, so much so that you will be able to set it up in as little as under a quarter of an hour.

Despite being somewhat more affordable than other units we have come across while completing our research process, this Orion will never disappoint you when you need it the most. 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. What this means is that while it is a good choice for typical sky watching, it might also prove to be a handy assistant for other activities, as well.
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. While you won’t be able to look at deep-sky objects with the help of this unit, it will inevitably prove its worth if you intend to look at bright planets and the moon.

Meade Instruments Infinity
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.
