  • As expected
Color: 90700-Black
I think it is nice! I gave as a gift to the man I thought I was dating as a gift. He told his girlfriend his mother gave it to him. He said he liked it?

  • Great quality at a great price.
I recently purchased this telescope, and I couldn't be more thrilled with its performance. From the moment I unboxed it, the quality was evident. The build is solid and sturdy, which makes it perfect for stargazing sessions, even in less-than-ideal weather conditions. Setup was straightforward, with clear instructions that guided me through the process seamlessly. The optics on this telescope are exceptional. The clarity and sharpness of the celestial bodies are breathtaking. I’ve been able to see the craters on the moon in stunning detail, and the rings of Saturn are more vibrant than I ever imagined. The focusing mechanism is smooth, allowing for precise adjustments with minimal effort. One feature I particularly love is the enhanced magnification. It’s ideal for both beginners and experienced astronomers alike, offering a great range of views without sacrificing quality. The telescope also comes with a smartphone adapter, making it easy to capture and share stunning astrophotography with friends and family. Overall, this telescope has exceeded my expectations in every way. Whether you're an amateur stargazer or a seasoned enthusiast, I highly recommend it for anyone looking to explore the night sky. An excellent investment! ... show more

  • Great telescope ❤️

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.

  • A perfect gift for stargazing
Color: B-90900
I purchased this telescope as a gift for my husband, and he absolutely loves it! The setup was relatively easy, and the instructions were clear, which made the whole process a breeze. The image quality is stunning — he’s been able to see so many details in the moon’s surface, planets, and even distant stars that we couldn’t have imagined. The magnification is strong but easy to adjust, and the stability of the mount keeps everything steady for long viewing sessions. My husband has always been fascinated by astronomy, and this telescope has reignited his passion for stargazing. It’s built solidly, and we can tell it will last for years. Whether you’re a beginner or experienced astronomer, this telescope is an excellent choice. It’s a fantastic value for the price, and I’m so glad I made this purchase ... show more

  • Amazing New Hobby!
Color: B-90900
The media could not be loaded. Brand new to the world of astrophotography but always had an interest in astrology to begin with so this telescope was a perfect way to combine both. Did a few days of research based on my interests then was pleasantly surprised to get this as a gift from my father, thanks pop's! From the unboxing to the assembly (carefully on both I may add) took about an hour. Luckily we live in a part of the city with higher elevation for a great field of view for stargazing so all was set... then as a beginner with little to no experience besides child-like wonder about the darkness behind the darkness you get introduced to mother nature and the proper conditions to view the cosmos, not hard to pick up or understand just didn't add that part in to my equation during my research. After a few weeks of practice and patience this was my best picture of the moon and first video with a planetary camera. The overall quality of this telescope is quite impressive and exceeded my expectations. Just after a few days of use, understanding positioning and what angle to set the mount for the best stable view on top of remembering the importance to be comfortable, again exceeded my expectations as far as the ease of use and quality of the view I was getting. Happy to say after a month of time with this telescope I'm even more excited as I first was to continue to learn and grow with this telescope! The one and only reason this doesn't get 5 stars is according to the description of this package was it included a digital eyepiece which unfortunately wasn't in the box with the telescope. I emailed the email address the instructions advised me to but to no avail. Still love this telescope and looking forward to continuing this journey. ... show more
