StellaLyra 62.5mm Elliptical Secondary Mirror (GSO)

These mirrors can be found in GSO-made Newtonian and Dobsonian Telescopes worldwide, and they are renowned for their combination of high quality and great value.

The glass used is optical grade BK7, and GSO guarantees diffraction-limited performance, although the mirror surface quality is typically around 1/16 wave RMS.
