Product Description

StellaLyra 8 inch f/4 M-LRN-D Carbon Fibre Imaging Newtonian Reflector with 2 inch Dual-Speed R&P Focuser
Designed and manufactured to a high standard by Guang Sheng Optical (GSO) in Taiwan.

This compact 8" 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 imaging Newtonian telescopes feature GSO aluminised parabolic primary mirrors with a minimum 94% reflectivity and a silicon dioxide protective overcoat to ensure the surface remains bright for years.

Optimised for deep sky Astrophotography:
Stiff Carbon Fibre Tubes to aid collimation and enhance focus stability
Dual Speed Rack and Pinion Focuser, which can handle heavy camera loads without slipping
Oversized Secondary Mirror for excellent illumination
The CF Tube is blackened internally for enhanced contrast
Central mark on the primary mirror to aid collimation
Includes a Losmandy-style mounting dovetail plus a Vixen-style dovetail on top
Note: For astrophotography, a coma corrector is required for optimum results.
