About this product

Model:  stellalyra_8_f4_newt
Part Number:  GS600

8" f/4 StellaLyra Imaging Newtonian Reflector Telescope

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

This 8" StellaLyra reflector with a fast f/4 focal ratio is an excellent choice for deep-sky imaging with a dedicated astronomy CMOS/CCD camera or DSLR. 

All StellaLyra Newtonian telescopes feature GSO aluminised parabolic primary mirrors with minimum 93% reflectivity and a silicon-dioxide protective overcoat to ensure the surface remains bright for years. Chunky collimation knobs enable easy collimation adjustment without tools, and an integrated fan reduces cooling time. 

The sturdy dual-speed 2" Linear Bearing (aka Monorail) Crayford focuser has enough tension for most small/medium size imaging payloads and provides precise, smooth focus adjustments. 

A nicely made 8x50 straight finderscope with fully multicoated optics is included and can be adapted (adapter available separately) for use as a convenient guide-scope. 

A 2"-1.25" adapter and 35mm focus extender are included for visual astronomy. 

It is supplied with metal tube-rings and a Vixen-style dovetail mounting plate. 

Note: For astrophotography, a coma corrector is required for optimum results.
