GSO

GSO (Guan Sheng Optical) is one of the largest manufacturers of telescopes and optical accessories in the world. For decades, the brand has provided reliable instruments popular with both beginners and advanced amateur astronomers. GSO's Dobson telescopes are especially popular for their rugged construction, user-friendly design and competitive pricing.

Dobsonians for everyone
GSO is known for its Newton/Dobson telescopes with mirror diameters ranging from 6″ to 12″ and larger. Thanks to their stable wooden rocker box, well-coated mirrors and smooth movements, these telescopes offer an ideal balance between simplicity and optical performance. Beginners appreciate the intuitive operation, while advanced observers enjoy the large aperture that gathers plenty of light for deep-sky objects.

Optical components and accessories
In addition to complete telescopes, GSO also produces high-quality optical components, including paraboloid main mirrors, diagonals, Barlow lenses and eyepieces. These components are used worldwide, including by other brands that have their products manufactured at GSO. This underscores the quality and reliability of their optics.

Who is GSO suitable for?

• Beginners: entry-level Dobson models (such as the 6″ and 8″) for moon, planets and the brightest deep-sky objects.

• Advanced: larger models and premium components for more detailed deep-sky observations.

• Builders and hobbyists: separate mirrors and accessories for those who want to assemble or upgrade their own telescope.
