TerryMcK Posted May 11 Share Posted May 11 That’s the second harmonic drive I’ve seen recently first from ZWO next from IOptron. Maybe SW and Celestron have others waiting in the wings. Quote Link to comment Share on other sites More sharing options...
GazAstro Posted May 11 Author Share Posted May 11 Quite an interesting twist on the new harmonic drive mounts, It uses the expensive harmonic on Ra but sticks with a 'normal' motor on the Dec to keep the cost down. Quote Link to comment Share on other sites More sharing options...
