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.

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.
