    • I saw Jupiter with my own eyes!!
Color: W-90900
I love my telescope! The magnification can go up to 450x, so I was able to view Jupiter clearly with my own eyes for the first time in my life! And I am able to see the wheels within wheels of stars like Sirius! That's exactly what I wanted. I especially love the high precision adjustment knobs because the objects travel outside the field of vision much faster than I realized they would. Using the high precision adjustment knobs I can easily keep the object in my field of vision. The adjustment knobs are a MUST HAVE! I also love the high quality tripod! It is critical that the telescope not move once you have zeroed in on your object. This tripod is stable and easy to adjust. LOVE IT! ... show more

    • I am definitely satisfied with this telescope 🥰
Color: W-90900
Review Image by Yevhen Sydorenko
It’s the first telescope in my life and it’s awesome. Has 4 linces, but I had success only with 3 of them, I am learning how to use them. Looked at the moon it was beautiful. I think that it works better, I just didn’t gave enough time to learn how to use it. Looks great at home. As far as I understand it’s not cheep and nice for begginners and mature stargazers. Thank you . ... show more

    • Nice scope for the price
Color: W-90900
I bought this telescope after looking and comparing several different models. It came packaged really well and all the parts were there. It was fairly easy to assemble. As a beginner it is easy to setup and use. I have only used it a couple of times because the weather hasn’t cooperated. The only negative thing that I can say is it is a little unstable when there is a lot of wind. I would recommend it for a beginner for sure. ... show more

Overall I’m very happy with this telescope. I’m working with it and learning more everyday, but I do wish it was a bit more sturdy. Other than that it’s a wonderful product.

    • Tripod is not stable
Color: W-90900
The telescope only is very good product, however I found the tripod very unstable, the image at close range still shakes. No matter what I tried if you barely touched and that the end of your fix. Very easy-to-use assemble, not very portable. The azmath and elevation very smooth, again just by adjusting the fine tunee know the tripod shakes totally unstable the manufacturer should consider upgrading the tripod to a better much for such good telescope. ... show more

    • Great beginner telescope
Color: W-90900
We bought this telescope for our son for Christmas. It is definitely better than the ones from when we were kids. The images are very clear, the moon looks amazing and our sons love looking through it. The base is fairly stable, and each eyepiece is good for the price. There is no better choice to see if you and your family will enjoy stargazing and looking at planets than this! Great intro telescope to get your kids into astronomy! ... show more

    • Awesome Telescope

This telescope is awesome! Bought it for my wife for Christmas and she absolutely loves it. It was really easy to put together right out of the box. Have got to use it much because it's been raining or cloudy a lot here recently but the times we have it has performed better than expected. We are amateurs for sure but this telescope has outperformed my expectations. ... show more

    • Wish I could see…
Color: W-90900
I had high hope for this telescope, but unfortunately, it turned out to be a complete disappointment. Write out the box. The set up was a little frustrating, but the videos that you can look up were really helpful, but given the camera angles on some steps, it leaves a lot to imagination on what to do. The telescope simply didn’t function as expected which was very upsetting. The focus was good for the moon but anything else the image was terrible and the image was blurry, no matter how much I adjusted it. I REALLY wanted to make this telescope work and believed it to be user error. I tired for weeks on clear nights but no matter how much I adjusted, nothing worked. To make it worse, I miss I missed the return window by just a few days so now I’m stuck with the telescope that doesn’t work properly. ... show more
