Rainbow Astro RST-300 GoTo Mount

Rainbow Astro RST-300 GoTo Mount

This mount uses sophisticated technologies for offering unique features:

Lightweight with only 8.5 kg
Although the load capacity is 30 kg (maximum 50 kg), the weight of the mount is only 8.5 kg.

Counterweights not required
Counterweights not required up to 30 kg. You can prevent accidents by the observer or guest from hitting the counterweight. Since there is no need for a weight bar, it is good for wide use of a narrow observation room.

Freed from balancing
The performance of the worm gear mount is sensitive to the balance, but the RST-300 is not. No problem with balancing two telescopes mounted side by side, no need to rebalance even if you change the eyepiece or camera.

Strain Wave Gear (Harmonic Drive)
Instead of worm gears, a new type of reducer called strain wave gear (harmonic drive) is used. Almost no backlash and no maintenance is required. As it is widely used in industrial robots, it is very durable.

Built-in brake
The RA axis has a built-in brake system. When the mount power is off, the brake is activated to prevent the "back drive" phenomenon. "Back drive" refers to the phenomenon that the shaft rotates in the direction of gravity when the power of the strain wave gear mount is turned off.

CNC Machining
CNC machined aluminum alloy AL6061 is used for aircraft. That´s why it´s small, light and stiff. The beauty of the machined surface increases the collection value.

WiFi
WiFi is built in. You can control the mount via the SkySafari app on your smartphone. The Ascom driver can be connected via WiFi as well as USB. GOTO and AutoGuide are now wireless.

GPS Receiver
GPS receiver is built in. The position and time of the observer can be entered accurately and conveniently.

Home Sensor
There is a built-in home sensor to find the mechanical origin. This is useful for permanently using Star Alignment data. Build an ultra-small remote observatory with the RST-300 mount.

Manuals
The manufacturer has created a manual with helpful information, for example about the connection plates for telescope and tripod, as PDF: rst-300-manual.pdf

There is also a manual for the hand controller as PDF: rst-135-hubo-i-manual.pdf
