Base for Newtonian focusers for tubes with diameter larger than 285mm

With this base you can attach several focuser models currently available on your Newtonian telescope. You can attach the base to the telescope using four M4 or similar screws (not included). We offer this base for different tube diameters. The base is designed for Newtonian focusers with a dovetail connection for adaptation.

Distances of the holes for screws attaching the base to the tube: 70mm parallel to the tube, 73mm sideways
