(b) When you let go with both hands, the tube should not drift up or down. - Page 6 to position the object in the center of the telescope’s eyepiece by turning the R.A. and declination slow-motion control knobs (the R.A. and Dec. lock levers must be tightened to use the slow-motion control knobs).

This “center mark” allows you to achieve a precise collimation of the primary mirror; you don’t have to guess where the center of the mirror is. You sim- ply adjust the mirror position (described below) until the reflec- tion of the hole in the collimation cap is centered in the ring.
