Guan Sheng GS-580 6" Limited
150mm x 1200mm

$349.00 AUD

First grade 6" (150mm x 1200mm) Dobsonian reflector with truly outstanding 1/12th surface wave primary and secondary BK7 mirrors.

Features a high grade 1.25" rack and pinion focuser.

Includes a 6 x 30 finderscope and GSO high-grade 9mm and 25mm  1.25" Plossl eyepieces!

Important notes re GSO mirrors...

GSO mirrors are guaranteed  diffraction limited. They achieve the theoretical limits of resolution for their respective surface areas.

GSO Newtonian Dobsonian telescopes have BK7 type glass paraboloidal mirrors, precision figured and polished to 1/12 average surface wave error.

I have witnessed this exacting and time consuming process numerous times, along with the confirming surface wave error printouts, in my several visits to the GSO factory in Taiwan.

The high industry standard for mirror surface wave error is 1/10 wave, yet very, very few telescope manufacturers regularly achieve it.

Due to recent quality improvements at GSO some optical products from GSO are now achieving a truly outstanding 1/16 surface wave error! Truly amazing - for the price!!
