Method to shoot the target (for reference)
1)
Sight the telescope to the bright sky. Turn the focusing ring until you can see the cross hair clearly.
2)
Aim the target by observing through the tip of the triangle on the telescope. Keep some distance
between your eyes and the eyepiece.
3)
Rotate the telescope focusing nob 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.
