Teflon strips to prevent tilting of the focuser on inexpensive telescopes


In inexpensive telescopes, the focuser often tilts. This is caused by the gap between the focuser and the drawtube being too large. On some telescopes, the tilt can be adjusted using two small grub screws. Where these screws are not available, we usually add thin Teflon strips to reduce the gap.

SkyWatcher sometimes takes care of this at the factory.
