Adjustment SkyWatcher focuser
The eyepiece tubes on SkyWatcher refractors often wobble. This means that the object being focused moves up and down when focusing.
This can be easily adjusted using the two small 3mm Allen screws. Tighten each of these until the focus tube becomes slightly harder to move. The locking screw must be loosened for this to happen.
If this isn't sufficient, Teflon strips can be used to minimize the gap between the drawtube and the focus tube. See the post below!
Good luck and clear nights!
