About this product
Part Number: GS800
10" f/4 StellaLyra Imaging Newtonian Reflector Telescope
Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan.
This 10" 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 3" Linear 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.
An adapter for 2" & 1.25" eyepieces and a 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.
