I bought the YENGUAN Telescope for Adults & Kids off Amazon with high hopes, and I’m thrilled to say it delivered way beyond what I expected—especially at this price point. I’ve been using it for a couple of weeks now, and whether I’m stargazing solo or with family, this telescope has made every night sky session exciting and memorable. Assembly and Build Quality: Setup was surprisingly straightforward—even for a first-timer like me. The instructions were clear, and all the parts were well-packaged and easy to identify. It took me less than 20 minutes to assemble it completely. The stainless steel tripod feels solid and sturdy, not flimsy like I expected from an entry-level model. The included carry bag is also a nice touch for portability—I’ve already taken it on a weekend camping trip. Performance: What really impressed me is the clarity of the images. The 90mm aperture and 800mm focal length combo offers crisp, detailed views. The Moon looks phenomenal—craters, ridges, and shadows are all incredibly sharp. I was able to spot Jupiter’s bands and even a few of its moons on a clear night, which blew me away. The 25mm and 10mm eyepieces, combined with the 3x Barlow lens, provide a solid range of magnifications, from wide views to zoomed-in details. User Experience: The finderscope is super helpful for lining up targets (though it’s inverted, which takes a minute to get used to). Focusing is smooth and precise, and the 45° erecting prism makes viewing comfortable for long sessions. The phone adapter works great—I’ve been able to snap some decent shots of the Moon and share them with friends and family. For Beginners and Casual Observers: This telescope strikes the perfect balance of being beginner-friendly without feeling “kiddie” or overly simplified. It’s a serious instrument that invites exploration but doesn’t intimidate. My younger cousin (age 10) was able to use it with a little guidance, and she was over the moon—literally and figuratively. Final Thoughts: If you’re looking for a reliable, well-made, and affordable telescope that can get you and your family into stargazing with minimal fuss, the YENGUAN telescope is absolutely worth it. The optics are clear, the build is solid, and it offers a ton of value for the price. I’m very happy with this purchase and look forward to many more nights under the stars. Rating: 5/5 – Highly recommended for beginners, hobbyists, and families looking for a quality telescope without breaking the bank.

Im absolutely stunned by the easiness of putting pieces together and later, usage of this telescope! I am already using it by looking through the window of my apartment. And I am absolutely mesmerized by it. I always wished to have a telescope. But I thought it’d still show everything in a blurry image. But didn’t imagine it’d be so clear. The reasons I preferred this telescope than others: 1. Price was better than others; 2. Accurate description and instructions: I can see that they’ve considered first time, amateur explorers. 3. Other telescopes that I saw, were very expensive and very-very professional. As I said, I’m just an amateur and would like to build up a foundation before buying a professional telescope. Next plans I have with the telescope: 1. Gotta take it outside and look into moon!! Yikes, can’t wait it!! 2. Learn how to use phone with the telescope and take photos! I’ll later either update or insert more details into my exploration with this telescope! Keep tuned :)

I love this telescope on dark nights! I have been looking for a telescope for a long time but didn't commit. I took a chance on this one because the price for the quality and the accessories was a great value. I am so glad I did it. As astronomy lover this will work perfectly for my family gatherings to watch the stars at night. The quality is great, not like other cheap plastic ones I had growing up. Set up was easy and the image was good. Sure a $1000 dollar would telescope give better image quality, but for the price this is a home run. Easy use for beginners and I highly recommend!

the Yenguan 90800 telescope is a promising option for people starting their astronomical journey. The large aperture, multi-coated optics, and included accessories like the Barlow lens and phone adapter offer a good starting point for exploring the night sky. It is extremely easy to use and setup. The quality of site is out of the world (pun intended) I absolutely recommend this. I wish I could give it more then 5 stars.

The media could not be loaded. I rarely write reviews, but this telescope truly deserves one. From the moment I unboxed it, I was impressed by the thoughtful packaging and the sturdy carrying case that fits everything perfectly. Setup was a breeze—even for someone like me who had never touched a telescope before. The instructions were clear, and I had it assembled and ready to go in under 10 minutes. Once I aligned the finder scope and got the hang of the focusing knob, the results were better than I expected. I started with daytime viewing—spotting birds and treetops from across a large field—and the image clarity blew me away. Later that night, I pointed it at the Moon and couldn’t believe the detail I was seeing. Craters, shadows, texture—it felt like I was right there. The included 10mm and 25mm eyepieces offer great flexibility, and the phone adapter was a fun bonus. I was able to take surprisingly sharp pictures just using my phone. The tripod feels solid, and the adjustable height makes it comfortable whether you're sitting or standing. I also appreciated how easy it is to pan and tilt—the movement is smooth and responsive. This is a fantastic telescope for beginners or casual observers who want something reliable, portable, and affordable. I bought it for myself but ended up sharing it with friends and family because everyone got excited after seeing what it could do. Great optics, simple design, and a price that’s hard to beat—definitely recommend it.

Got here fast. Was a little worried as the box had a couple small holes. Scope and all the other contents were perfect. Very easy set up and the phone adapter is great. Only issue has been the barlow is not great. Haven’t been able to use it and focus on things. Without the barlow it works great.
