Sky-Watcher Flextube 250P SynScan

254mm Aperture with 94% Reflectivity Coatings

At the heart of the Flextube 250P is a 254mm (10-inch) borosilicate primary mirror. This large aperture gathers 57% more light than an 8-inch model, resolving down to a limiting magnitude of 14.5. Sky-Watcher's Radiant Aluminum Quartz (RAQ) coatings ensure 94% of that light reaches your eyepiece, producing brighter, higher-contrast views of faint nebulae and distant galaxies.

SynScan GoTo with 42,900+ Object Database

The computerized SynScan system transforms this Dobsonian into a powerful discovery tool. After a simple two-star alignment, the hand controller can automatically slew the telescope to any of the 42,900+ objects in its database. The Freedom Find dual-encoder system is a critical feature; it allows you to move the telescope manually to a new target without losing your alignment, giving you the best of both push-to and GoTo functionality.

Flextube Design: from 44" to 31.5"

Large aperture no longer means an impossibly large telescope. The patented Flextube design allows the optical tube to collapse from a fully extended 44 inches down to a compact 31.5 inches. This makes transport and storage simple, allowing you to easily fit the 33 lb optical tube and 39 lb base into a standard vehicle for trips to dark-sky sites.

• Quick Setup: The truss tube system doesn't require disassembly. It transports as two main pieces and can be set up in seconds.
• Tension Control: A patented Tension Control Handle lets you adjust the friction on the altitude axis, ensuring smooth motion even with heavy eyepiece and accessory combinations.
• Collimation Stability: The rigid truss design holds collimation well throughout an observing session, a known trade-off for the fast f/4.7 optical system that demands precise alignment for the sharpest views.

Flextube 250P vs. 200P: A 57% Light-Gathering Advantage

For observers deciding between the 10-inch 250P and its 8-inch sibling, the primary difference is light grasp. The Flextube 250P's larger mirror provides a significant boost for viewing faint deep-sky objects.

• Flextube 250P (10-inch): Gathers 57% more light, making nebulae like the Veil Nebula (NGC 6960) appear brighter and more detailed, and resolving more stars in globular clusters like the Hercules Cluster (M13).
• Flextube 200P (8-inch): A capable and even more portable option, but the 250P offers a noticeable step up in image brightness and resolution that dedicated deep-sky observers will appreciate. The added aperture comes with an increase in weight, with the 250P's OTA and base weighing 33 lbs and 39 lbs respectively.
