Replace focuser

Replacing the focuser using an example from a SkyWatcher refractor:

The original SkyWatcher focuser can be easily replaced with, for example, a Baader STEELTRACK Crayford focuser.

To do this, you need to loosen the three screws on the focuser adapter. Instead of the focuser, the Baader adapter of the new focuser fits exactly into the existing holes. Now, the new focuser is lightly tightened to the adapter with three grub screws.

Then, check the alignment and readjust if necessary.
