I was looking for a beginner telescope for a while now and was looking for something that was economical. This one caught my eye but was a little out of range of what I wanted to spend, but being patient helped and saw this on come down within my range on Black Friday and decided to buy it. So far so good. Enjoying stargazing with my 12 year old over the Thanksgiving break. Packaging : Good. The telescope came packed in a cushioned bag that can be used to carry it on trips. The bag was packed inside a box which in turn was packed with protective packing and an outer box. Assembly : Very easy with clear instructions both pictorial and written making it easy to follow. Do and Don'ts clearly laid out. Telescope : The telescope itself is not very heavy making it easy to carry/move around during use or on trips. The two lenses ( 10mm and 25mm) provide good magnification for lunar observation and viewing other stars/planets like Jupiter . I was able to use the 10mm lens and get a clear view of Jupiter with its 3 largest moons on Day two of use ( beginner's luck , I guess), proving this is easy to setup and start using. Within 30 mins of unpacking I was already gazing at the sky taking in sights of Venus and Jupiter. The phone adapter holds the phone securely although using it takes some getting used to since touching the phone while being focussed on a planet/star might affect the picture. I found using a remote bluetooth camera trigger or smartwatch app for clicking picture to be very helpful. All in all a good starter telescope to get your astronomy juices flowing.

I live in the Mojave Desert in Nevada, where light pollution is practically nonexistent — and this Yenguan Telescope absolutely blew me away! With its 90mm aperture and 800mm focal length, I was expecting decent performance, but what I got far exceeded my expectations. The quality of the lenses is surprisingly high, especially given the affordable price. The image of the moon was absolutely stunning — crisp, clear, and incredibly detailed. I could easily make out craters and surface features I’ve never seen so vividly before. Setup was a breeze. Everything came carefully packaged and assembly took just minutes. The height-adjustable tripod is sturdy and smooth to use, and the included 10mm and 25mm eyepieces, Barlow lens, and finder scope give you plenty of options right out of the box. The smartphone adapter looks simple to use — I haven’t tried it yet, but I’m excited to start capturing some night sky photos soon. The durable carry bag is a thoughtful touch and makes transporting the scope easy. Whether you're a beginner or someone who just enjoys stargazing from time to time, I can’t recommend this telescope enough. Fantastic quality, easy to use, and perfect for anyone lucky enough to have a clear night sky.

I recently got this telescope, and it has been a great experience so far. The setup was simple, and it came with a nice carrying case, which makes it easy to take anywhere. The build quality is solid, and the included accessories, like the eyepieces and phone adapter, are a great bonus. The image quality is impressive for the price. The large aperture allows for clear and bright views of the moon and planets, and even some deep-sky objects can be seen with decent clarity. The multi-coated optics help improve sharpness, making stargazing a lot more enjoyable. The tripod is stable enough for general use, though a sturdier one would improve the experience even more. The phone adapter is a fun addition, making it easy to capture images of what you see. Overall, this is a great telescope for beginners and hobbyists. It’s easy to use, portable, and provides clear views of the night sky. Definitely a solid choice for anyone looking to start their astronomy journey.

Bought this for my fiancé, after getting it all set up and figuring out how to use it it wouldn’t work, even after watching several videos on the same exact one couldn’t get it figured out.

I recently purchased it for my daughter’s birthday gift and it has been an amazing experience for both her and me! The setup was easy with clear instructions that made assembly quick and hassle-free. The build quality is solid, and the sturdy, adjustable tripod makes it comfortable for adults and kids. The viewing experience has been fantastic. While we didn’t have many clear nights after the purchase, we were able to capture craters of the Moon in detail over the last weekend. The brightness and clarity made stargazing exciting for my 8 years old daughter. It is now her best toy and she absolutely love it! She was amazed at how close the Moon looked and was thrilled to point the telescope at different stars. It’s not at all difficult for her to move and use it. Watching her excitement while exploring the night sky made this purchase completely worth it! Overall, this telescope is a fantastic choice for families, beginners, and anyone looking for a high-quality yet easy-to-use telescope. Highly recommended!

It was very difficult for us to set up and figure out how to use it. I still have it in the trunk of my car hoping to one day be able to actually use it to watch all of the incredible celestial events going on right now.

I recently took the plunge and purchased a telescope for my 7-year-old son, and I must admit, I was initially hesitant about the investment. However, this telescope has truly exceeded my expectations and has proven to be worth every penny! It might just be the best value for the money that you can find in a beginner's telescope. From the moment we unboxed it, my son was filled with excitement. One of the standout features is how easy it is to assemble—no tools are needed, which is such a relief for parents! Within minutes, we had it set up and ready to go, allowing us to dive straight into our first stargazing adventure. What truly sets this telescope apart is its compatibility with an iPhone. The ability to take amazing pictures of the sky and stars has been a game-changer for us. Capturing those celestial moments together has not only created lasting memories but has also sparked a genuine interest in astronomy for my son. Watching his eyes light up as he sees the craters on the moon or the rings of Saturn is priceless. This telescope makes for a perfect gift for Christmas and is an ideal choice for anyone just starting in this wonderful hobby. It encourages curiosity, exploration, and learning about the universe in a fun and engaging way. I wholeheartedly recommend this telescope to any parent looking to inspire a love for the stars in their child. It’s a fantastic way to bond and share the magic of the night sky!
