PORTA features a newly designed friction system allowing quick slewing to objects and 360° slow-motion controls for tracking. No fumbling with clutches or sectional slow-motion controls that run out of travel! Leave the heavy counterweights with the equatorials: simply balance scopes up to 155mm diameter on the altitude axis and start viewing! Standard Vixen dovetail mounting slot with lock and safety screw is fully SPHINX/GP-compatible. Mounting slot removes to reveal 1/4-20 and M8-1.25 threaded holes for custom mounting solutions.
