How to adjust the magnification of the telescope:
1. Pull the Monocular All The Way Out: Pull the Barlow all the way out, to the longest status. (IMPORTANT!!!) Otherwise, you cannot get the clear sight from the spyglass.
2. Look at the End of the Glass with the Smaller Diameter: Point the objective lens to the object and look through from the eyepiece.
3. Adjust the Eyepiece to Get Clear Sight: Slightly push the Barlow in bit by bit for focusing till you can see the object. Clear views will come to you finally if you slightly operate to change the Barlow length.
