CRUX-170HD review

Harmonic Drive I’ve received a brand-new ‘Harmonic Drive’ equatorial mount CRUX-170HD about a month ago. CRUX-170HD uses a special driving mechanism different from other equatorial mounts. Baisically, almost all commercially-available equatorial mounts are worm-driven. They uses worm and worm gear system for final reduction. But there are few drawbacks here. Worm & worm gear system […]
