Flanges for Hybrid-Drive focusers on Newton optical tubes

Our flanges allow you to install the 50,8mm Newton Hybrid-Drive focuser on Newtonian optical tubes, providing a side that fits perfectly to the curvature of the optical tube. Made entirely of black anodized aluminum, these models come standard in our carbon fiber Newton optical tubes.

Compared to the universal flange offered standard in the 50,8mm Newton Hybrid-Drive focuser, they fit perfectly to the curvature of the optical tube for which they are designed and this prevent the entry of unwanted light from the side of the focuser. Each flange has four holes for mounting the optical tube with normal M6 screws.
