StellaLyra 6" f/4 M-LRN-D Carbon Fibre Imaging Newtonian Reflector with 2" Dual-Speed R&P Focuser

The StellaLyra 6" f/4 Carbon Fibre Imaging Newtonian Reflector is a lightweight, fast focal ratio OTA tailored for wide-field deep-sky imaging. Designed and built in Taiwan by Guan Sheng Optical (GSO), this compact telescope offers high-contrast performance with durable mechanics and superb optical quality — ideal for astrophotographers using CMOS, CCD or DSLR cameras.

Capture the Cosmos in Fine Detail

At just 530mm in length and 5.3kg in weight, the StellaLyra 6" Carbon Fibre Newtonian delivers impressive deep-sky results in a portable package. The fast f/4 focal ratio makes it well-suited for imaging faint nebulae and galaxies, while the carbon fibre tube ensures thermal stability and helps maintain precise collimation throughout your session.

Key Features

Enhanced Reflectivity Optics:
Parabolic 150mm aluminised primary mirror with 94% reflectivity and a protective quartz (SiO₂) overcoat, delivering crisp, bright imaging.

Oversized Secondary Mirror:
62mm minor axis with 94% reflectivity provides strong edge illumination, ideal for astro imaging sensors.

Carbon Fibre Tube:
Strong, lightweight construction resists flexure and temperature-related expansion. Internally blackened for improved contrast and reduced stray light.

Dual-Speed Rack & Pinion Focuser:
Stable, smooth focusing performance with excellent payload capacity — ideal for imaging setups.

Optimised for Collimation:
Primary mirror includes a central mark to aid accurate alignment in the field.

Flexible Mounting:
Supplied with a Losmandy-style dovetail rail underneath and a Vixen-style dovetail bar on top for mounting accessories or a guidescope.

Note: A coma corrector is required (not included) for best results when imaging at f/4.
