The Bresser AR102 powerful achromatic refractor in carbon fiber, is the core of this telescope. The compact tube with a diameter of 102mm and a focal length of 600mm is equipped with a sturdy 2" metal focuser. Already included is a 50,8mm (2") to 31,7mm (1.25") eyepiece adapter. So both of the most common eyepiece sizes can be used for this telescope. Two Kellner eyepieces (25mm and 10mm) are part of the set. The solid EQ3 mount and the height adjustable aluminum tripod form the base for stable observations. This complete set is also ideal for traveling star observers due to its compact size. It can easily be assembled and disassembled and thus can be stowed space-saving in a car.
