About this product

Model:  stellalyra_6_f8_dob

High performance 6" f/8 Planetary Dobsonian telescope! 

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

With 6" aperture, a long f/8 focal ratio and only 22% secondary obstruction, this easy to use Dobsonian telescope is an excellent choice for observing the Moon and planets. 

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, Jupiters weather bands and a number of its Moons and Saturn with its rings, including the Cassini division, are also clearly visible.

Whilst the long focal length suits higher magnification visual observations, the 6" aperture and high contrast optics also provide excellent views of brighter deep sky objects like M42 / Orion Nebula or Galaxies like M81 and M82.

All StellaLyra Dobsonian telescopes are fitted with a quality GSO aluminised parabolic primary mirror with 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. 

This 6” model also features a surprisingly good CNC-machined 1.25" Crayford focuser for smooth, accurate focusing and zero image shift.

A fully multicoated 1.25" 25mm Plössl eyepiece is included so views will be clear and sharp, from the outset.  

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

Teflon pads in both axis provide smooth movement and tension can be adjusted to achieve just the right amount of resistance.

In Altitude a spring tension system prevents the telescope from moving during eyepiece changes.
