    CG-5 Mount - Precision engineered for stability
    The German Equatorial mount has precision worm gears on both axes for extremely smooth stability. The key element that makes this system the most stable in its class is the heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. The CG-5 also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments
