About this product
Model: stellalyra_6_f4_newt
Incredible value 6" f/4 StellaLyra Imaging Newtonian Reflector Telescope
Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan.
This compact 6" StellaLyra reflector with fast f/4 f/ratio is an excellent choice for deep-sky imaging with a dedicated astronomy CMOS/CCD camera or DSLR.
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 to come.
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.
For visual astronomy a 2"-1.25" adapter and 35mm focus extender is included.
Supplied with metal tube-rings and Vixen-style dovetail mounting plate.
Note: For astrophotography a coma corrector is required for optimum results.
