The 2-inch Concenter uses a central viewing aperture and concentric reference rings to align a Newtonian telescope.
Alignment method
Its transparent disc helps compare the edge of the secondary and mirror reflections with concentric circles. Secondary placement relative to the focuser is checked before its tilt and the primary alignment; no centre mark on the secondary is needed.
Use
Insert it into the matching focuser socket and follow the manufacturer’s collimation sequence. A protective container is supplied.
