Best Intermediate Telescope 2021
With so many models with so many features available today, it can be a tedious task to find the best intermediate telescope. We have analyzed the main features ( aperture, focal length, ratio, portability, affordability etc.) that make a good telescope for intermediates that you can use to enjoy the night sky and fulfill your love for astronomy.
Best For Beginners
Celestron – AstroMaster 130EQ
The Celestron PowerSeeker 127EQ telescope is a Newtonian reflector, which means it uses mirrors to gather the light of the skies, and reflects it for viewing. With mirrors being much less expensive to produce than glass lenses, reflector telescopes offer more value in terms of inches of aperture.
The PowerSeeker 127EQ comes with two eyepieces (4mm and 20mm) and a 3x Barlow lens.
The 5-inch mirror on the 127mm PowerSeeker model limits useful magnification to about 250x, which is achieved using the 4mm eyepiece.
The larger 20mm eyepiece provides a more useful 50x magnification. This grows to 150x when coupled with the 3x Barlow.
If you’re considering an additional eyepiece, something like a 15mm Plossi would be a good option. This provides you with 66x magnification, or 198 when coupled with the Barlow.
The telescope is ideal for near and deep-sky observation, Celestron’s PowerSeeker 127EQ 127mm f/8 Reflector Telescope features a respectable focal length and a large, parabolic mirror that produce detailed images of the Moon, clear views of the planets, and the ability to resolve bright distant objects such as nebulae and galaxies.
The beauty of a Newtonian telescope is the longer focal lengths which can be offered in much shorter tube sizes—1000mm focal length in a tube which is only 20 inches (508mm) long .
The PowerSeeker 127EQ is highly portable and one of the best intermediate telescope for adults & teenagers alike. You could easily fit this telescope and tripod in the trunk of a car and still have room for your other equipment, or maybe a late night picnic.
Additionally, you receive a copy of Starry Night astronomy software with a database of over 10,000 celestial objects.
Considering the telescope’s low price, compromises had to be made, and one such compromise is the use of a spherical mirror rather than a parabolic mirror.
Optical aberrations tend to be more common with spherical mirrors. This telescope does, however, feature an erect image diagonal for the right way up images, which prevents some aberration.
This telescope comes with an Equatorial mount, designed for astronomy telescopes. Included are two manual slow-motion controls, these allow for smoother tracking of objects as they pass across the night sky.
The tripod is made of aluminum, although lightweight, it is robust, solid and also comes with a very handy accessory tray which lets you keep extra eyepieces and T-rings for a camera, close to hand.
- Solid build quality
- Stable mount
- Comes with a 3x Barlow lens
- Spherical mirror leads to some amount of aberrations
- Occasional collimation of the mirrors required

Best Intermediate Telescope Buying Guide 2020
Buying a telescope for home use is an important step towards a new level of appreciation for the night sky, and the wonders found within it.
The decision to level up and purchase an intermediate telescope is huge, and if you choose the right product, it can completely change your life and how you view life on Earth.
The ability to see deep into the cosmos has a profound effect on most people, and fortunately, it’s much easier to do than you might think.
For a breathtaking planetary viewing experience every time, it is important to make sure you’re purchasing a quality product – not something you’ll find at most department-stores.
The telescope you want has two essentials: high-quality optics and a steady, smoothly working mount. You may also want the telescope to be nice and large, but don’t forget portability and convenience.
Features To Consider When Choosing A Good Intermediate Telescope
The most important aspect of any telescope is its aperture, the diameter of its main optical component, which can be either a lens or a mirror.
The aperture of a telescope is the diameter of the light collecting region, assuming that the light collecting region has a circular geometry . For an optical instrument, the aperture is the diameter of the objective lens (refracting telescope) or the primary mirror (reflecting telescope). The larger the aperture, the more light the telescope can gather, and the fainter the limiting magnitude of the instrument. The field of view of the telescope decreases as the aperture increases, but the resolving power increases.
The focal ratio (f/5.9 for example) is the ratio between the aperture and the focal length. Multiply the aperture by the f ratio to find the focal length.
Focal length is the distance between a telescope’s primary optics and the image it creates. A longer focal length is more suited for observing planets, while a shorter focal length is better for wide field views of space.
To get an image suitable for observing with our eyes, a telescope uses a second lens, or collection of lenses, called an eyepiece at the focal plane. The eyepiece magnifies the image from the objective.
The eyepiece also has a focal length. The magnification of a telescope and eyepiece is very simple to calculate. If the focal length of the objective is “F” and the focal length of the eyepiece is “f”, then the magnification of the telescope/eyepiece combination is F/f. For example, if a telescope has an objective lens with focal length of 1200 mm (about 48”) and it has an eyepiece of focal length 25 mm (about 1”), then it will have a magnification of 1200/25=48x.
The eyepiece determines the magnification of the view through your telescope. Divide the focal length of your telescope by the focal length of the eyepiece to find the magnification. Eyepieces come in focal lengths ranging from 2mm to 56mm.
The highest useful magnification for a telescope is about twice the aperture size in mm. For example a telescope with a 150mm aperture is limited to a 300x magnification before the view will become too blurry. But this also depends on your atmospheric conditions while observing and on the quality of your optics.
Eyepieces come in 2 sizes: 1.25 inches and 2 inches. A 2″ eyepiece requires a 2″ focuser but a 1.25″ eyepiece is more versatile. It’s usually the higher end eyepieces that come in the 2″ size and they tend to be heavier and more expensive.
Types Of Mounts
The mount is a very important part of the telescope. Some types of telescopes are better suited for a particular type of mount. There are 4 main types.
Alt-azimuth mounts are the simplest type of mount, and they are similar to a camera tripod. They allow you to move the telescope up and down and side to side. But it can be difficult to track the stars and make precise adjustments. For this reason they are mainly suited for smaller, low-power telescopes.
Equatorial mounts allow a telescope to track the sky as Earth rotates. They do this with motor drives but do not necessarily require a computer system to track, although some equatorial mounts are computerized for finding objects.
Most equatorial mounts are German equatorial mounts, which use counterweights to balance the telescope. This type of mount is versatile and breaks down into smaller pieces, making even large telescopes portable.
The dobsonian is a variation of the alt-az mount, designed for reflectors. Instead of using tripod legs, it uses a heavy base that is often made of wood. This is a stable design that doesn’t cost a lot and allows for more precise movements.
A fork mount is designed for shorter tube telescopes (usually the compound type). They are motorized and do not require a counterweight since the telescope is balanced at it’s center of mass. But they are often heavier than other types of mounts.
Types Of Telescopes
There are 3 main types of telescopes:
This is the classic design that most people picture when they think of a telescope. Light enters through a lens at the top of the telescope before bouncing off a diagonal mirror at the bottom to the eyepiece. Smaller aperture refractors can be found for a low price, but larger aperture designs quickly become very expensive.
A reflector telescope contains a large concave mirror at the bottom of a tube which bounces light toward a secondary mirror at the top and then to the eyepiece. Larger reflectors may use an open truss design instead of a tube to save weight. A reflector is one of the most cost-effective designs that allows you to get the most aperture for your money. This is especially true if used with a dobsonian base.
A compound (or catadioptric) telescope is made with a combination of mirrors and lenses. It is the most complex type, but this usually results in a more compact and lightweight design compared to the others.
