About this product

Backyard Universe Secondary Spider for GSO/StellaLyra 150mm Newtonian Telescopes

This CNC-machined secondary spider is made of black anodised aluminium (EN AW-6061) and is suitable for GSO (StellaLyra, TS, etc) manufactured 6" Newtonian telescope. 

High precision manufacturing ensures the 1.8mm thickness struts are perfectly aligned, making the diffraction-induced spikes on bright stars razor-sharp. 

The lightweight, stable design is optimised using FEM simulation to improve collimation stability significantly.
