Mark III is a lightweight and portable German equatorial mount with a delicate harmonic gear system. Despite its lightweight of 7.95kg, Mark III boasts outstanding payload capacity, quick dynamic response and accurate data-transmission and processing. It’s a great option for astro-observation or astrophotography, and a handy and functional helper along your journey to the universe exploration.
