Sky-Watcher Explorer 250PDS - The ultra-bright Newton 10″ for deep-sky enthusiasts

Visit Sky-Watcher Explorer 250PDS is a 254 mm diameter Newton telescope, designed for demanding amateur astronomers who want to explore in detail the most discrete objects in the deep sky, while enjoying excellent performance on the Moon and planets. With a 1200 mm focal length and f/4.7 focal ratio, it offers a perfect balance between brightness, field and precision.

A 254 mm mirror: an opening that changes everything

With an aperture of 25.4 cm, this telescope captures more than 1270 times more light than the human eye, revealing faint galaxies, subtle nebulae and distant clusters with astonishing clarity. The diffraction-limited parabolic mirror maintains remarkable sharpness even at high magnification, while offering optimal contrast on the lunar surface or Jupiter's cloud bands.

Precise focusing with Crayford DualSpeed

The 2″ Crayford-type focuser, mounted on ball bearings, guarantees smooth focusing even with heavy accessories such as cameras or wide-field eyepieces. The 1:10 gearing allows micrometric adjustment ideal for high-resolution photography and the perfect focus on diffuse objects.

A fast, open Newton for photography

With its f/4.7 ratio, the Explorer 250PDS is a fast instrumentideal for reducing exposure times in astrophotography. Mounted on an EQ6-R, AZ-EQ6 or equivalent, it becomes a formidable machine for capturing planetary nebulae, spiral galaxies or large Hα complexes.
