How-To Laser Collimate a Newtonian Reflector
Below are the simple steps for using a laser collimator to collimate a Newtonian reflector telescope.
- Using a ruler center the Spider at the top of the OTA and loosen the primary mirror locking nuts.
- Turn the collimator on and place in the focuser of the scope.
- Using an Hex/Alan key adjust the secondary mirror so the laser is pointing at the exact center of the primary mirror (most larger scopes have a 'doughnut' in the center to help with this) this is best done with the scope laid down in case you drop the Alan key
- Tighten all bolts/screws on the secondary mirror so it cant move. Steps 3 and 4 will only need to be done occasionally.
- To align the secondary mirror adjust the primary mirror bolts so the laser hits the center of the target within the collimator.
- Lock the primary mirror with the locking bolts this completes the collimation.
