The AP-SM mount is an enhancement of the AP mount. Unlike the AP mount, it has an RA motor and is equipped with the STARBOOK ONE controller.

The AP mount provides a secure, stable support for your telescope. Thanks to the slip clutch mechanism, the mount can be adjusted quicky to the target object.

There is a wide range of optional accessories. The ADVANCED POLARIS mount is ideal for both beginners and advanced observers who require a lightweight travel mount.

The AP mount features an ultra-smooth finish without any projecting parts. Simply place your telescope on the mount and move it to the desired celestial object without having to loosen any clamps!

The slip clutches allow you to adjust the telescope to your target object easily – no more searching for adjustment clamps in the dark! An optional polar meter is available, which enables you to locate the celestial pole when it is hidden by trees or buildings.

The innovative polar finder scope provides a new way to polar align your telescope. Simply align the stars in the crosshair reticle with the same stars in the night sky. Polar alignment is achieved using 3 reference stars. The polar finder is illuminated to facilitate orientation and switches off automatically after 3 minutes to save battery power.

The RA and DEC motor modules are powered by four AA alkaline, Ni-MH or Ni-CD batteries. The RA motor module has a USB Micro-B port for an external power supply. A USB power pack or car charging cable can be used for longer observation sessions.

The STAR BOOK ONE is a multifunctional and intuitive controller that tracks in the RA and DC axis with a range of different speeds. The tracking options are designed for time-lapse cameras at a wide range of speeds, including sidereal, lunar and solar rates. The controller also offers many useful functions such as backlash compensation, autoguider port, PEC and a built-in red LED light.
