1. Take the cap off the Barlow Lens. Do not unscrew the lens from the barrel. Might be a good idea to check it is clean, if you have unscrewed it its probably covered in sticky fingerprints by now.
2. Insert the Barlow lens into the focusser, the skinny end (where the lens is) goes into the focusser, the fat end (empty) sticks out of the focusser.
3. Insert eyepiece into the fat end of the Barlow.
4. Try focussing the telescope.
