Description

StellaLyra 8" f/6 Dobsonian Telescope

Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan. 

With an 8" aperture, this easy-to-use Dobsonian telescope is an excellent choice for visual astronomy.

Viewing the lunar surface will feel like you can reach out and scratch plaster! Venus and its phases are also viewable. In good seeing conditions, you can observe Mars with surface shading and polar cap, Jupiter's weather bands and a number of its Moons and Saturn with its rings, including the Cassini division, are also clearly visible. So too, are many deep sky objects such as galaxies and nebulae. For many owners, this telescope will provide a lifetime of observing. 

All StellaLyra Dobsonian telescopes are fitted with a quality GSO aluminised parabolic primary mirror with a minimum 93% reflectivity and a silicon-dioxide protective overcoat to ensure the surface remains bright for years to come.  

Collimation knobs on the primary mirror cell provide easy collimation adjustment without tools, and an integrated fan provides fast cooling. 

This 8” model also features an impressive CNC-machined 2" Crayford focuser with 1:10 dual-speed focus adjustment for smooth, precise focusing. And no image-shift!

The focuser includes a 2" to 1.25" adapter, so you use both 2" and 1.25" eyepieces and accessories. Brass compression rings grip them securely without marring their nosepiece. A convenient 35mm focus extender is also supplied so you can achieve focus easily when using most long focal length 2" eyepieces. 

Three fully multicoated eyepieces (1.25" 9mm Plössl, 1.25" 15mm Plössl, and 2" 30mm SuperView) are included, so views will be clear and sharp from the outset.  

The Dobsonian base is delivered flat-packed and is easy to assemble. 

A robust roller-bearing assembly provides smooth, reliable azimuth adjustments. Metal plates above and below the bearings prevent them from sinking into the softer wood (no divots!), so the movement remains smooth, even after years of use. 

For altitude adjustment, a robust steel shaft and CNC-machined metal plates with large knurled tension adjustment knobs, one on each side, provide smooth, precise movements and adjustable tension. 

The mount also features a convenient balance adjustment mechanism with an engraved scale that enables the telescope to be moved forward or backward for precise balance. This is useful when changing from a small eyepiece to a large, heavy one or when adding a second finderscope or binoviewer. 

For comfort and convenience, a Right-Angled Correct Image 8x50 finder scope is included, so no cricked neck!  

NOTE: The assembly instructions are generic for 8", 10" & 12" models, so please don't be concerned if your telescope is supplied with fewer screws than shown in the instructions. You will have the correct number.

8x50 Right-Angled Finderscope

  • Cross-hair reticule for precise alignment
  • Two adjustment screws and a sprung loaded tensioner make it quick and easy to align the finderscope to the main telescope (it can be aligned during daytime when aimed at a distant pylon, but be careful not to point it anywhere near the Sun)! 

Primary Mirror Cell

  • Robust primary mirror cell holds collimation well.
  • Collimation is easily adjusted using oversize, easy-to-grip adjustment and locking knobs.
