APM 2" Quick Lock adapter for focuser with M68 OD Thread

The new Q-Lock eyepiece clamp from APM is a solid and high-quality extension of your telescope or camera system. The unique, coaxial clamping mechanism always keeps your accessories safe and tilt free! Non correct fixed eyepieces, tubes or cameras are a thing of the past! The 120°-angled pressure cylinders fix the connected accessories over 3 points, so they are ultimately safe. Even heavier accessories are held securely. A 90° movement of the rotating sleeve already reaches from the open position up to the maximum pressure. The holding force can be very sensitively adjusted, even sensitive accessories are optimally protected. The large locking screw can also be used sensitively for friction and clamp adjustment. The very high-quality mechanism runs absolutely backlash-free and full. We offer you a very high product level at an amazingly low price!
