One of the most prominent telescope manufacturers in the country brings astronomy enthusiasts of all levels a piece of equipment perfectly designed for viewing the universe. The Celestron NexStar 130SLT comes with a 130mm lens diameter and a 650mm focal length, giving users plenty of range to observe the details of planets and even surrounding nebulas.
Paired with simple mounting and a sturdy tripod, this is one of the best telescopes for just about any scenario. Our favorite feature has to be Celestron’s native database of celestial objects. The telescope’s SkyAlign procedure can help locate and target up to 40,000 stars, galaxies, and more.
However, if you find yourself inspired to explore astrophotography, you’ll want to check out some better-stabilizing mounts. The Altazimuth style is fine for observation but won’t keep the telescope still enough for long exposures.

Best Alternative: Gskyer AZ90600
- 【High Quality Optics】600mm(f/6.7) focal length and 90mm aperture, fully coated optics glass lens with high transmission coatings creates stunning images and protect your eyes.
- 【High Magnification】Come with three replaceable eyepieces(24X, 60X,120X) and one 3x Barlow lens. 3x Barlow lens trebles the magnifying power of each eyepiece
- 【Adjustable Tripod】This telescope allows for many different viewing positions with a adjustable aluminum tripod. The height of aluminum tripod can be adjusted from about 31.5-inch to 49-inch
- 【Easy to Operate】No tools are required for reflecting telescope even for the novice, quick and easy to focus
- 【What You Get】AZ90600 telescope with 3 eyepieces, our 12-month worry-free support and friendly customer service.
While our best overall brings everything you could ask for to study the stars, its price tag can seem daunting for the first-timer. If you’re wanting to dip your toes into astronomy without the significant investment, you’ll have to check out the Gskyer AZ90600.
This German-designed telescope features comparable specs at half the price. Just know that with telescopes, you get what you pay for. The AZ90600 is great for observing the solar system, although its capacity falls short in just about every category.
For the money saved, you’ll have only a 90mm lens diameter, 600mm of focal length, and a more frail tripod. The Gskyer telescope also doesn’t feature a celestial database; while it’s not required for astronomy, it’s certainly more engaging to know what you’re looking at.

How to Pick the Best Telescopes for Stargazing
When choosing the right telescope to view the night sky, there are four main considerations.
- Lens diameter
- Focal length
- Mounting
- Price
Let’s review each one in more detail.
Lens Diameter
Arguably the most critical aspect to consider when looking at the best telescopes for stargazing is the diameter of the lens. This number represents the measurement across the center of the lens and determines the amount of light your optical tube can collect.
This correlates with sharper and more detailed images. If you have an object in mind that you want to observe, first determine if the lens diameter is large enough to view it.
Focal Length
The next aspect to look at for observing objects in deep space is the focal length. This number represents the distance between the telescope’s primary mirror and the focal point. Generally, the focal length correlates with magnification; the telescopes with larger focal lengths can view farther objects.
Of course, this number should pair well with the lens diameter. If you’re trying to view the extent of your optical tube without enough light, your objects won’t come out defined.
Mounting
Those that plan on viewing and exploring the universe past our solar system or want to venture into astrophotography will want to understand how mounting affects their images. While a simple Altazimuth mount with a tripod is acceptable for observing the moon or surrounding planets, a simple shake can set telescopes off trajectory for objects further off. When you need a mounting system that you can rely on, consider Dobsonian or Equatorial designs.
Price
Because of their intricate nature, you’re hard-pressed to find a telescope worth buying for under $200. Manufacturers can reduce costs using aluminum materials and reflective lenses.
It’s important to know that with the best telescopes, the price directly relates to quality. That means for a solid, Newtonian telescope, prepare to spend no less than $600.
What to Know Before Buying a Telescope
If you’ve taken a look at these products and you’re ready to get started, you’ll want to consider that no telescope can overcome inclement weather. Whether you settle for a $200 starter tube or a $2,000 apochromatic viewfinder, an overcast sky means you’re not looking at anything.
So before you even start looking at telescopes, you should investigate regional weather patterns. If you live in a typically cloudy location, you should either find a better place to observe or look for a different hobby.
The same goes for light pollution; a clear sky has little value if your target objects are washed out. Unfortunately, light pollution doesn’t go away overnight, so if astronomy is something you’re interested in pursuing, you’ll want to find a darker location. To find one around you, a dark map can help determine the best places to see stars, meteors, and other celestial objects around you.
Using the Best Telescopes: What It’s Like
When testing the best telescopes for any level astronomer, users focused on object clarity first. As expected, the optical tubes with the shortest lens diameter revealed fewer details than those with larger ones. Users were particularly impressed with the Orion SkyQuest XT8, which could pinpoint specific craters on the surface of the moon along with Saturn’s rings and the Orion Nebula.
Those with less experience using telescopes also preferred the models with automatic tracking. The Celestron NexStar 130SLT shined with its massive database of 40,000 objects, which allowed aspiring astronomers the opportunity to identify celestial bodies they wouldn’t have known otherwise.
The defining aspect that separated the models’ ease of use was the mounting design. The telescopes with Altazimuth mounts, such as the Celestron and the Gskyer, were simple to set up and led to quick star gazing.
The other Dobsonian stand threw some users through a loop, making its point of entry higher than others. And the Sky-Watcher EvoStar 120, with its separate Equatorial mount, required an additional purchase, making it more of an exclusive choice.
