Part Number: GS 500
StellaLyra 6" f/5 Newtonian Reflector Optical Tube
Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan.
The StellaLyra 6" F5 Newtonian telescope offers high-quality optics in a compact optical tube.
With its f/5 focal ratio, this telescope has good potential for astrophotography whilst being a little easier to collimate than its F4 brother.
All StellaLyra Newtonian telescopes feature GSO aluminised parabolic primary mirrors with a 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-sized imaging payloads and provides precise, smooth focus adjustments.
A nicely made 6x30 straight finderscope with fully multicoated optics is included.
The telescope is supplied with metal tube-rings and a Vixen-style dovetail mounting plate.
Note: For astrophotography, a coma corrector is required for optimum results.
