About this product

Model:  stellalyra_10_f4_newt

Incredible value 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 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 to come. 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. 

For visual astronomy an adapter for 2" & 1.25" eyepieces and a 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.
