Rated 1 out of 5

Difficult to Impossible to Make Usable

Cannot caliber or collimate to make telescope usable. Instructions are vague and/or non-existent. Found Youtube video showing how to collimate using a laser collimator which required another purchase to make usable. Still not working. Currently using as very expensive dish towel rack.

Easy to collapse and transport. Assembly was a breeze.

Find the universe at your fingertips with the Sky-Watcher Flextube 250P Collapsible 10" Dobsonian Telescope, a stylish and durable instrument that promises to elevate your stargazing experiences. This high-quality telescope is designed for the avid amateur astronomer who demands both performance and convenience. The innovative truss-support concept allows for a seamless collapse of the optical tube's front and back cells, ensuring that the telescope is user-friendly and can be effortlessly transported and stored by a single individual.

The Sky-Watcher Flextube 250P boasts a substantial 10-inch aperture, providing superior light-gathering capabilities that result in brighter, clearer, and more detailed images of celestial wonders. Whether you're observing the intricate structures of the Crab Nebula (M1), the sprawling arms of the Triangulum Galaxy (M33), or the delicate petals of the Rosette Nebula, this telescope reveals the cosmos with an impressive clarity that smaller apertures cannot match.

With the Flextube 250P, you'll witness the grandeur of deep-space objects like the Lagoon (M8), Trifid (M20), and Swan (M17) nebulae, as well as the breathtaking star clusters M13 and M92 in Hercules, with a brilliance and extension that will leave you in awe. The Great Orion Nebula (M42) and the vast Andromeda Galaxy (M31) are also displayed in their full glory, showcasing the incremental resolving power of a 10-inch aperture over its 8-inch counterparts.

The telescope's user-friendly design is complemented by its 1.25" eyepiece diameter, which offers a wide field of view for expansive observations. The Flextube 250P is not just a telescope; it's a gateway to the cosmos, providing an unparalleled viewing experience that makes it the preferred choice for serious amateur astronomers looking to step up their game.

Choose the Sky-Watcher Flextube 250P Collapsible 10" Dobsonian Telescope for its blend of innovative features, ease of use, and exceptional viewing power. It's not just an investment in a telescope; it's an investment in countless nights of discovery and the endless joy of exploring the heavens.

  • An 8x50mm Right Angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies when star-hopping
  • To ensure mechanical ease-of-use, SW uses a high-performance Teflon bearing system in both axes combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction
