The Rainbow Astro RST-300 is a revolutionary equatorial mount featuring strain wave gear (harmonic drive) technology borrowed from industrial robotics, delivering virtually zero backlash with minimal maintenance. Despite its remarkably compact 8.5kg weight, it supports payloads up to 30kg without requiring counterweights, making it ideal for mobile observatories, remote setups, and astrophotography. The mount eliminates the balance sensitivity of traditional worm gear systems, includes wireless WiFi connectivity with SkySafari app control, integrated GPS receiver, and a built-in RA axis brake system, all backed by a five-year warranty.
