About this product

Part Number:  GS 630

StellaLyra 8" f/5 Newtonian Reflector Optical Tube

Designed and manufactured to a very high standard by Guan Sheng Optical (GSO) in Taiwan. 

The StellaLyra 8" F5 Newtonian telescope offers high-quality optics in a compact optical tube.

With its f/5 focal ratio, this telescope has good potential for astrophotography whilst being a little easier to collimate than its F4 brother.

All StellaLyra Newtonian telescopes feature GSO aluminised parabolic primary mirrors with a minimum 93% reflectivity and a silicon-dioxide protective overcoat to ensure the surface remains bright for years. 

The sturdy dual-speed 2" Linear Bearing (aka Monorail) Crayford focuser has enough tension for most small/medium-sized imaging payloads and provides precise, smooth focus adjustments. 

A nicely made 8x50 straight finderscope with fully multicoated optics is included.

The telescope 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.

StellaLyra 8 f/5 M-LRN Newtonian Reflector with 2 Dual-Speed Focuser
26 January 2024  | 

I had been researching for months on my next imaging telescope, and came across a YouTube video that did a review on this scope. I found this to be sold by First Light Optics out of the UK. I placed my order with them and a week later it was delivered to me here in the US. The package was well labeled to handle with care and packaged very well. First Light Optics was quick to ship and was easy to order from. Very happy with my purchase and with FLO!!! Will certainly purchase from them again! Great company, great scope at a great price!!! Thank you FLO!!!
