Method to shoot the target (for reference)

$1·          Sight the telescope to the bright sky. Turn the eyepiece until you can see the cross hair clearly.

$1·         Collimate the target by observing through the tip of the cross hair on the collimator. Keep some distance between your eyes and the collimator.

$1·         Rotate the telescope focusing knob until the object can be seen clearly.

If there are deviations when moving your eye up, down, left or right, it proves that the focus or the diopter of the eyepiece is not adjusted well, which will affect the observation accuracy. You should focus and adjust the eyepiece sleeve carefully to eliminate such errors.
