Feature

Super small and lightweight

The mount weighs only 3.3kg. Plus, it fits in one hand, so you don’t need a big bag for the mount.

Counterweights Not Required

Counterweights not required. Of course, no effort is required to balance.

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.

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. 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-135 mount.
