Fornax-150 mount without controller and polar finder

German-type mounts. The mounts are composed of aluminium alloy, cast aluminium, bronze and stainless steel. The motors and the worm gear-drive are put in a heavy case, reducing the risks of pollution. Clutches are placed on both axes.
Both are ideal for astrophotography.
Can be use with various motor controllers, such as FS2, Boxdoerfer DynostarX3, MC4, Gemini Pulsar, etc...
Polarscope is optional (on request).
