Stella Lyra 8" f/5 Newtonian Reflector Optical Tube

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

The Stella Lyra 8" F5 Newtonian offers high-quality optics in a compact optical tube.

With its f/5 focal ratio, this telescope has excellent astrophotography potential whilst being a little easier to collimate than its F4 brother.

All StellaLyra imaging 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. 

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.

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.
