I remember my first time looking through a proper telescope. It wasn’t a high-end observatory instrument, but a simple refractor set up in a friend’s garden. The target was Saturn. After some fumbling with the focus knob, the planet snapped into view—a tiny, perfect orb suspended in a set of ethereal rings. That single moment transformed the night sky from a flat tapestry of dots into a deep, three-dimensional universe filled with worlds I could actually see. It’s a feeling every budding astronomer chases. The problem is, the journey often starts with a daunting choice. Many entry-level telescopes are little more than toys, offering shaky mounts and blurry optics that lead to frustration, not discovery. Conversely, high-performance scopes can carry price tags that are simply out of reach for a new hobbyist. The challenge is finding that perfect middle ground: a telescope powerful enough to reveal the wonders of the cosmos, yet user-friendly and affordable enough to make the journey enjoyable from the very first night.

What to Consider Before Buying Your First Astronomy Telescope
A telescope is more than just an item; it’s a key solution for anyone curious about the universe, transforming abstract celestial concepts into tangible, breathtaking views. It’s a scientific instrument that serves as a gateway to a deeply rewarding hobby, offering a unique blend of education, relaxation, and pure awe. For families, it’s a tool for shared discovery, pulling children away from screens and into the vastness of space. The main benefit lies in its ability to gather light, revealing details utterly invisible to the naked eye—from the rugged craters and mountains on our own Moon to the distant, swirling bands of Jupiter’s atmosphere and the faint, ghostly glow of a faraway nebula. A good beginner telescope demystifies the night sky and fosters a lifelong appreciation for science and our place in the universe.
The ideal customer for this type of product is someone taking their first serious steps into astronomy. This includes curious adults, families looking for an educational activity, or students wanting a hands-on tool for their science interests. They are looking for a complete, all-in-one package that removes the guesswork and provides clear, rewarding views without a steep learning curve or a prohibitive cost. However, a model like this might not be suitable for seasoned astronomers who require advanced features like GoTo computerized tracking or apochromatic lenses for high-level astrophotography. Likewise, someone who needs an ultra-compact scope for backpacking might find this full-sized kit, while portable, a bit too cumbersome. For them, a smaller tabletop Dobsonian or high-quality binoculars might be a better starting point.
Before investing, consider these crucial points in detail:
- Aperture & Focal Length: Aperture (the diameter of the main lens, here 90mm) is the most critical specification. It dictates how much light the telescope can gather, which determines how bright and sharp the images will be. A larger aperture allows you to see fainter objects and more detail. Focal length (here 800mm) influences the telescope’s magnification potential and field of view. A longer focal length like this one is generally excellent for getting detailed, high-power views of planets and the Moon.
- Mount Type & Stability: A telescope is only as good as its mount. The Dianfan 90mm Aperture Refractor Telescope uses an Alt-Azimuth (AZ) mount, which moves in simple up-down and left-right directions. This is highly intuitive and perfect for beginners. The material of the tripod is equally important; the stainless steel construction here provides far better stability than the flimsy aluminium tripods common in this price range, minimizing frustrating vibrations.
- Optics & Included Accessories: A good telescope should come with quality, multi-coated lenses to maximize light transmission and reduce glare. The value of a package is significantly enhanced by the included accessories. Look for at least two different eyepieces (for low and high magnification), a Barlow lens (to increase magnification further), and a finderscope to help locate objects. Extras like a phone adapter and a carrying case, as included here, are tremendous bonuses.
- Ease of Use & Portability: Your first telescope should invite you to use it, not intimidate you. Look for tool-free assembly and clear instructions. Portability is also a key factor. While you can observe from a city balcony, the best views are often found away from light pollution, so a telescope that comes with a dedicated carry bag for easy transport is a significant advantage for star-gazing trips.

A Deeper Look: Performance of the Dianfan 90mm Aperture Refractor Telescope
A telescope’s true worth is revealed under a dark sky. Beyond the specifications and accessories, it’s the quality of the view through the eyepiece that matters most. We spent several clear nights putting the Dianfan 90mm Aperture Refractor Telescope through its paces, targeting a range of celestial objects to test its capabilities, from our closest neighbour to the gas giants of the outer solar system. Here is our detailed breakdown of its performance.
Optical Prowess: The 90mm Lens in Action
The heart of this telescope is its 90mm achromatic objective lens. In the world of beginner telescopes, where 60mm and 70mm apertures are common, this jump to 90mm is significant. This larger aperture gathers substantially more light, resulting in brighter, clearer images with better resolution. Our first target was the Moon, and the view was simply breathtaking. Using the 25mm Plossl eyepiece (providing 32X magnification), the entire lunar disc was framed perfectly, showing sharp contrast between the bright highlands and dark maria. Bumping up the power with the 10mm eyepiece (80X), we could easily explore individual crater systems, tracing the shadows cast by their towering rims and central peaks. This experience was echoed by numerous users, with one noting they could observe “lunar craters clearly” and another stating the moon was “impressively detailed to see.”
Moving on to the planets, we found Jupiter to be a spectacular sight. Even at 80X, the planet’s two main equatorial bands were distinctly visible, and the four Galilean moons appeared as sharp, bright pinpoints of light orbiting the gas giant. The real test came with Saturn. We used the 10mm eyepiece combined with the 3X Barlow lens to push the magnification to 240X. While atmospheric conditions cause some softness at such high power (a universal challenge), the iconic rings were unmistakably separate from the planet itself—a moment that never fails to elicit a gasp of wonder. Many satisfied owners confirmed these capabilities, reporting that “Saturn’s rings and Jupiter with its moons are clearly recognizable.” The telescope’s 800mm focal length and f/8.8 focal ratio provide a fantastic balance, offering enough power for detailed planetary observation while still being capable of framing brighter deep-sky objects like the Orion Nebula or the Pleiades star cluster. For its price class, the optical performance is genuinely impressive and a feature that really sets it apart.
From Box to Backyard: Assembly, Stability, and Ease of Use
One of the biggest hurdles for aspiring astronomers is the initial setup. A complex or poorly documented assembly process can end a hobby before it begins. Dianfan has clearly prioritized a user-friendly experience here. As mentioned, our own setup time was under 15 minutes, a sentiment strongly supported by user reviews. One owner happily stated, “In just 10 minutes I assembled it following the instructions,” while another noted, “assembly was quicker than I expected… in less than half an hour we had it ready.” The illustrated, multi-language manual is clear and easy to follow.
Once assembled, the telescope’s stability becomes the next critical factor. This is where the stainless steel tripod truly shines. It provides a solid, steady foundation that dampens vibrations quickly. When focusing or making slight adjustments with the slow-motion control rod on the AZ mount, the image settles almost immediately. This is a night-and-day difference compared to cheaper telescopes that wobble for several seconds after being touched, making high-magnification viewing nearly impossible. The AZ mount itself is perfect for beginners. Its simple, intuitive point-and-look operation allows you to glide smoothly across the sky, tracking objects as they move without the complex polar alignment required by equatorial mounts. This ease of use makes it a joy to operate for both adults and children, encouraging exploration rather than causing frustration.
The Complete Package: Analysing the Included Accessories
A telescope is a system, and the quality of its accessories directly impacts its performance and value. The Dianfan 90mm Aperture Refractor Telescope comes with a thoughtfully curated kit that provides everything a beginner needs to get started. The two included eyepieces—a 25mm and a 10mm—are of the Plossl design, which is a significant step up from the cheaper Kellner or Huygens eyepieces found in many starter kits. The 25mm offers a wide field of view at low power (32X), perfect for locating objects and observing large star clusters. The 10mm provides a higher-power view (80X) for zeroing in on planetary details and lunar features.
The inclusion of a 3X Barlow lens adds incredible versatility. This small device triples the magnification of any given eyepiece, effectively turning the two eyepieces into four different magnification options (32X, 80X, 96X, and 240X). This allows you to adapt your view to different objects and atmospheric conditions without buying additional accessories. Another standout feature is the smartphone adapter. While users correctly note that it requires some patience and a steady hand to align perfectly (“using it with the mobile… requires a bit of practice”), it opens the door to basic astrophotography. We were able to capture some genuinely impressive photos of the Moon, immortalizing the view through the eyepiece. The final, and perhaps most praised, accessory is the carry bag. Reviewers consistently celebrate it as a “fantastic bag to transport it,” and for good reason. It makes the entire system genuinely portable, allowing you to easily take it on camping trips or to dark-sky locations for an unforgettable night under the stars. This comprehensive kit transforms the telescope from a mere instrument into a complete, ready-to-go astronomy solution. You can check the latest price and availability here.
What Other Users Are Saying
Across the board, user feedback for the Dianfan 90mm Aperture Refractor Telescope is overwhelmingly positive, particularly among beginners and families who are its target audience. The sentiment we found in our own testing is widely confirmed. One user, thrilled with their purchase, commented, “The quality of the images is sharp and detailed, perfect for those who are starting out but want to obtain professional results.” Another highlighted its performance by stating, “With the variable magnification from 32x to 240x, not only can the moon and planets be observed wonderfully, but you can also take a first look into the world of deep-sky objects.”
The praise isn’t limited to the optics. The robust build and complete accessory package are frequent points of celebration. “The stainless steel tripod is stable and you can tell it’s good quality, which is important when children are going to use it,” one parent noted. The carry bag and phone adapter are consistently mentioned as significant value-adds that elevate the entire experience. Of course, no product is perfect. Some users found the initial alignment of the small finderscope a bit fiddly, and there’s a consensus that mastering the phone adapter takes a bit of practice to avoid vibrations, but this is seen less as a flaw and more as part of the learning curve of a new hobby.
How Does the Dianfan 90mm Compare to the Competition?
While the Dianfan 90mm is a formidable contender, it’s important to understand its place in the market. Here’s how it stacks up against three popular alternatives.
