Complete telescope set with AP mount, APP-TL130 tripod, eyepieces and SD 81S refractor telescope

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 mount requires four AA batteries, which are inserted inside the AP mount. This prevents unnecessary cable clutter and reduces the risk of pulling the cables or knocking the mount over in the dark.

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 newly developed APP-TL130 tripod provides portability and stability for astronomical observations. Measuring just 60 cm when retracted, it is ideal for on-the-go use. The tripod can be extended to a height of 130 cm. The ends of the tripod legs have a retractable rubber cover that protects the floor against scratches.

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.  The STAR BOOK ONE controller is designed for the AP-SM mount and is an integral part of the RA motor module.

The apochromatic refractors from Vixen feature an optical Super Extra-Low Dispersion SD glass in the objective lens. The SD glass produces a clear and high-contrast image free from false colours.

This gives the observer a colour-neutral, sharp and very high-contrast image.

The SD 81 has 81 mm lenses and a 625 mm focal length. Weighing just 3.6 kg, it is also very portable

and is suitable for use on smaller mounts.

The large focuser allows you to attach heavy cameras without the telescope tilting.

The telescope also comes with a folding mirror for making observations in unfavourable conditions,

as well as a T2 thread for connecting a DSLR camera.
