Sky-Watcher Flextube SynScan 250P Dobsonian Telescope

The Flextube design is engineered to maintain collimation even after the tube is collapsed and extended. While you may need to perform minor adjustments after transport, the rigid truss structure ensures the optics remain aligned for consistent performance.

Yes. Thanks to the Freedom Find dual-encoder technology, you can move the telescope by hand to point at objects without disengaging the motors or losing your alignment data. Once you stop moving it, the computer knows exactly where the telescope is pointing.

While this is primarily a visual instrument, it is capable of short-exposure lunar and planetary imaging. However, because it is an Alt-Azimuth mount, it will experience field rotation during long-exposure deep-sky photography, which limits its use for that specific application.

The mount requires a 10-15V DC power source. Most users opt for a portable power tank or a dedicated lithium-ion battery pack to ensure stable voltage throughout a night of observation.

At 72 lbs total weight, this is a substantial piece of equipment. The collapsible tube makes it much easier to fit into a standard vehicle compared to a solid-tube Dobsonian, but you should expect to move it in two pieces—the base and the optical tube—to make setup manageable.

You have the flexibility to use either. The integrated Wi-Fi allows you to control the telescope wirelessly using the SynScan app on your smartphone or tablet, providing a more intuitive interface than the physical hand controller.
