Review Summary

Rated 2 out of 5

Scope great - manufacturing horrible.

The scope itself works great... Once you get it aligned properly and fix the manufacturing issues. Mine arrived with a loose secondary mirror, as well as none of the screws for the truss being uniformly installed or tight.. one set of them was about 5 mm above flush, one set was flush, and one was counter sunk 3 or 4 mm. Additionally, the collimation was such that only 1/3 of the primary mirror was visible, the rest of it was telescope wall. After buying a collimation eyesight and tightening the loose bolts, it works great for planetary astrophotography.

A telescope worth owning.

The optics are great, the mount is solid, and it tracks well. My only significant complaint is the lack of adjustable feet to level the scope on uneven ground. Minor gripes are the eyepiece holder is too shallow to hold the large eyepieces I use (Baader and Celestron), and the secondary adjustment screws are hard to see in the dark. Overall I'm pleased with the telescope, but 5 stars are not warranted.

So far assembled and tested! Just waiting on a clear sky to observe the Moon and stars. So far nothing but positive reviews and recommendations.

Why settle for anything less than a telescope that combines the timeless simplicity of a Dobsonian with the cutting-edge technology of a Go-To system The Sky-Watcher Flextube 10" 250P Synscan GOTO Collapsible Dobsonian is a marvel of modern astronomy equipment, designed for both the seasoned stargazer and the enthusiastic beginner eager to explore the cosmos.

Crafted with precision engineering, this telescope offers a seamless stargazing experience, allowing you to effortlessly locate and observe a myriad of celestial wonders, including planets, nebulae, star clusters, and distant galaxies. The patented collapsible tube design is a testament to Sky-Watcher's commitment to innovation, offering unparalleled portability without compromising on performance.

The Flextube Dobsonian's elegant truss tube design is not just about aesthetics; it's a functional masterpiece that ensures ease of use and consistent viewing excellence. This design negates the need for time-consuming disassembly, as the telescope can be transported as two compact pieces and swiftly assembled in seconds, ready for your astronomical adventure.

Once set up, the telescope maintains its collimation throughout the night, ensuring that your viewing experience remains high-quality and uninterrupted. The patented Tension Control Handle is a feature that adds to the user's convenience, allowing for the adjustment of tension to modify the friction between the optical tube and the sideboards, ensuring smooth and precise movement.

The SynScan AZ hand control is the gateway to the stars, offering automatic slewing to over 42,900 celestial objects with a simple button press. The user-friendly menu system is designed for quick mastery, even by astronomers with little to no experience. The patented dual encoder design further enhances the experience by allowing manual movement of the telescope without the need for re-alignment, providing both freedom and flexibility in your stargazing sessions.

While the telescope has received acclaim for its solid mount and exceptional optics that ensure clear and crisp images, user feedback has highlighted areas for improvement such as the addition of adjustable feet for leveling on uneven ground and a deeper eyepiece holder to accommodate larger eyepieces. The secondary adjustment screws could also benefit from enhanced visibility in low-light conditions.
