ตัวแปลง GSO 2" to 1.25" Self-Centering Adapter (สำหรับใช้ eyepiece ขนาด 1.25" ใน Diagonal/ฟอกัสเซอร์ ขนาด 2")
The new twist-lock system allows locking 1.25" accessories dead-on to the optical axis, removing possibility of accessories being tilted or off-center, as well as problems of safety grooves being trapped in compression rings. By twisting the ring, a 15 mm high Nylon chuck closes around the nosepiece. It is then held gently but securely in the center. Pressure is not concentrated to one point but around the complete surface area of the eyepiece barrel. On the telescope side, there's a 2" filter thread. Technical details:
