The Skywatcher extension tube fits direct on to an EQ5 or HEQ5 mount for use with refractor telescopes. The EQ5/HEQ5 extension tube extends the height of the EQ5 and HEQ5 mount so it is easier for observer to look into a long refractor. Installed between the tripod and the mount head, this heavy-duty metal tube adds about 16″ in height to the assembly while maintaining the stability of the mount.
