Notice:

In order to ensure that you are seeing the best images your telescope is capable of providing, you should collimate your telescope before each use. Additionally, you should collimate your telescope any time images become blurry.

Ensure that the secondary mirror is square ly under the focuser. You should see all three retaining clips for the primary mirror reflected in the secondary.

Use the 2’’ adapter sleeve if you intend to use 2’’ eyepieces and place the laser into the focuser with the window pointing towards the primary mirror end of the telescope and switch it on.

Wave your hand in front of the telescope and see if the laser is exiting without hitting the secondary on the return. Also look through the side window of the laser collimator to see if the laser is returning to the face of the laser.

Adjust screws 1, 2, or 3, or a combination to move the laser into the middle of the primary mirror centre spot.

If the return beam is not parellel with its origin, you will have to move the collimation screws on the primary mirror. A final test can be done on a star

Warning:

Do not look directly into the laser beam! Permanent eye damage may result!

Avoid prolonged skin exposure to laser rashes or burns may occur!
