StellaLyra 8" Dobsonian Telescope – Premium 203mm GSO Reflector

The StellaLyra 8" Dobsonian Telescope is one of the finest 203mm Newtonian reflectors available in the UK, combining premium Guan Sheng Optical (GSO) optics with exceptional mechanical quality for a lifetime of visual astronomy.

With its 203mm parabolic primary mirror, this telescope delivers outstanding views of the Moon, planets, galaxies, nebulae, and globular clusters. Lunar observing is razor sharp, Jupiter’s cloud bands and moons are beautifully resolved, Saturn’s rings and Cassini Division are clearly visible, and under dark skies deep-sky objects become truly spectacular.

The precision 1200mm focal length at f/5.9 strikes the ideal balance between planetary contrast and wide-field deep-sky performance, making this a superb all-round Dobsonian for beginners and experienced observers alike.

Premium GSO Optical Performance

At the heart of the telescope is a high-quality BK7 parabolic primary mirror with a minimum 93% reflectivity aluminium coating and durable SiO2 protective overcoat. This ensures bright, contrast-rich views for years to come.

The robust primary mirror cell features large hand-adjustable collimation knobs for quick tool-free alignment, while the integrated cooling fan helps the optics reach ambient temperature faster for sharper observing.

Precision Dual-Speed Crayford Focuser

A premium CNC-machined 2" dual-speed Crayford focuser with 10:1 fine focus reduction allows smooth, backlash-free focusing with no image shift.

• 2" to 1.25" adapter included
• 35mm focus extension tube supplied
• Brass compression rings protect accessories
• Ideal for premium eyepieces and coma correctors

Smooth Dobsonian Mount with Precision Balance Control

The supplied Dobsonian base is engineered for stability and effortless manual tracking. A roller-bearing azimuth system provides smooth 360° motion, while adjustable altitude tension clutches allow precise balance when switching between lightweight Plössls and heavier 2" eyepieces.

A built-in balance adjustment system with engraved scale makes it easy to fine-tune the tube position when adding accessories such as binoviewers, heavy wide-angle eyepieces, or a second finder.
