StellaLyra 8 Inch f4 M-LRN Newtonian Reflector with Dual-Speed Focuser

Product Description

An 8 Inch F4 StellaLyra Imaging Newtonian Reflector Telescope Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan. This 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 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 2" Linear Bearing (aka Monorail) 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.

A 2"-1.25" adapter and 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.

Updated July 2024: New improved focuser with a flat base makes attaching an EAF bracket much easier.
