StellaLyra 6 Inch f4 M-LRN-D Carbon Fibre Imaging Newtonian with Dual-Speed R&P Focuser

Product Description

StellaLyra 6 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 6" 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: Aids collimation and focus stability
Dual Speed Rack and Pinion Focuser, which can handle heavy camera loads without slipping
Oversized Secondary Mirror for excellent illumination
CF Tube is blackened internally for excellent reflection control
Central mark on the primary mirror to aid collimation
The Fast Focal Ratio is ideal for capturing faint nebulae and other DSOs
Includes a Losmandy-style mounting rail
Note: For astrophotography, a coma corrector is required for optimum results.
