Orion Optics UK 350mm Dobsonian Mount

This mount is designed for 350mm (approximately 14-inch) Newtonian telescopes. It can physically accommodate any optical tube with an outer diameter up to 385mm, providing a secure and stable base for instruments in this aperture class.

Yes, the simple design is excellent for beginners and seasoned astronomers alike. A Dobsonian mount is operated by hand, which is the most intuitive way to explore the night sky. There is no need for polar alignment, power supplies, or computers; you simply point the telescope where you want to look.

Dobsonian mounts like this one from Orion Optics UK utilize low-friction bearing surfaces for both altitude (up-down) and azimuth (left-right) movements. This allows you to make fine, controlled adjustments with gentle hand pressure to keep planets like Jupiter or Saturn centered in the eyepiece, even at high magnifications.

This mount is designed for visual astronomy. While you can take short exposures of the Moon and bright planets (a technique called "lucky imaging"), its alt-azimuth design is not suitable for long-exposure deep-sky astrophotography. For that, an equatorial mount that tracks the rotation of the Earth is required.

Dobsonian mounts are typically shipped flat-packed and require some assembly. This usually involves basic hand tools to assemble the rocker box and ground board. Once constructed, placing your optical tube in the cradle is a straightforward process.

Proper balance is crucial for a Dobsonian. While the mount is built for a 350mm-class OTA, the final balance will depend on your specific combination of finder scope, eyepiece, and other accessories. If the tube is front-heavy or back-heavy, you may need to add small counterweights or adjust the tube's position in its rings to achieve smooth, effortless motion.
