I’m very satisfied with the Koolpte telescope and pleasantly surprised by its overall performance. The build quality feels solid and well-made, especially considering the price. Setup was straightforward and beginner-friendly, with clear instructions that made it easy to get started right out of the box.

I recently purchased a telescope, and I couldn’t be happier with my choice. This telescope has truly exceeded my expectations in every way. Here are five reasons why I’m giving it a 5-star review: 1. Outstanding Clarity: The optics on this telescope are exceptional. I’ve been able to observe celestial objects with stunning clarity, from distant galaxies to the craters on the moon. 2. Easy Setup: Setting up this telescope was a breeze. It came with clear instructions, and I had it ready for stargazing in no time. 3. Sturdy Build: The telescope feels robust and well-built. It’s clear that the manufacturer paid attention to durability and quality. 4. Smooth Movement: The mount and controls allow for precise and smooth movements, making it easy to track objects across the night sky. 5. Value for Money: Considering the performance and features, this telescope offers excellent value for the price. It’s a fantastic investment for any amateur astronomer. Overall, I can’t recommend this telescope enough. It has brought the wonders of the universe closer to me than ever before, and I’m thrilled with my purchase. If you’re passionate about astronomy, this telescope is a must-have.

The KOOPLTE 70mm refractor delivers bright, clear views of the Moon and planets with multi-coated optics and easy setup. Portable tripod, phone adapter, and remote add convenience—great entry-level choice for beginners.

Telescope is nice for the price (you get what you pay for) but is super unsteady. To try & get your object in view is difficult as the slightest movement of the knob used to focus will throw your whole alignment off. I haven’t tried using the cell phone attachment yet but it makes me wonder how steady it will be with a phone hooked up. Spend a little more to get a better one if I were you. But again, it’s decent for the price. One good thing is the tripod extends pretty well so it’s at standing height.

Bought this telescope for my son’s birthday and he absolutely loves it. It’s easy to setup, took me about 10 minutes. He spent hours looking up at the sky last night, completely fascinated.

The media could not be loaded. When I bought this telescope, I could not find any images of what it capable of. So here is my review. It has different lens 20mm, 10mm, 6mm and barlow (which gives even more magnification but I was not able to make smartphone photos with it). Working with 10mm was easy 6mm gives much better magnification but it much harder to point at something (even after changing the tripod to better one) barlow lens practical was impossible to use with smartphone since it was bendeded under smartphone weight. I was able to see with barlow but it was too faint and unable to point to something specific as it moved too much. So here are images of bridge which is 13km (8miles) away. You can actually see the cars).
