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.
Mark III equatorial mount is powered by Onstep, a fantastic open source software. We would like to express our sincere gratitude to the developers and all relevant contributors who have helped a lot to improve the Onstep software. We will also do our best to make possible improvements and modifications to Onstep based on the practical operations to make this software and thus our equatorial mount perform more smoothly.
