Rainbow Astro RST-300 Mount: Robust Performance in a Compact Package

No Need for Counterweights: Revolutionizes traditional telescope mounting by eliminating the need for counterweights, even with a load capacity up to 30kg.
Remarkably Lightweight: Weighs only 8.5kg, significantly lighter compared to traditional worm gear mounts, enhancing portability and ease of use.
High Load Capacity: Despite its lightweight build, it can handle a substantial capacity of 30kg, with a maximum limit of 50kg.
Innovative Strain Wave Gear Technology: Employs strain wave gear (harmonic drive) for precision movement, virtually eliminating backlash and maintenance concerns.
Built-in Brake System in RA Axis: Features a unique brake system to prevent back drive, ensuring safety and stability when the mount power is off.
CNC Machined Aluminum Construction: Made of durable aluminum alloy AL6061, known for its strength and lightness, with a beautifully machined surface.
Versatile and Safe for Narrow Spaces: Ideal for use in limited spaces due to the absence of a weight bar, reducing accidents caused by counterweights.
Balance-Insensitive Performance: Unlike worm gear mounts, it's not sensitive to balance changes, perfect for mounting multiple telescopes or changing accessories.
Wireless Connectivity: Built-in WiFi for remote control via the SkySafari app and ASCOM driver compatibility, offering wireless GOTO and AutoGuide functions.
Integrated GPS and Home Sensor: Comes with a built-in GPS receiver for precise positioning and a home sensor for maintaining alignment data, ideal for setting up a remote observatory.
5-Year Warranty: Includes a comprehensive five-year warranty, providing long-term reliability and customer assurance.
