and the ROTARION AUTOFOCUS has lost your
focuser mechanical coordinate and is not
focusing correctly.
To correct it, the user must synchronize again
the focuser mechanical coordinate with a
previous focused object used during the
TRAINING procedure in the Current Position
counter. To proceed choose one of the
following reference values from the selector
ResetPos (42) drop-down list.
Reference values:
PORT-1 NEAR: Position for NEAR object in
eyepiece PORT-1
PORT-1 FAR: Position for FAR object in
eyepiece in PORT-1
PORT-1 VFAR: position for VERY FAR object in
eyepiece in PORT-1
30000: Intermediate focuser coordinate of
telescope travel. Recommended for
Schmidt Cassegrain and similar
telescopes with internal primary
mirror displacement.
0: Maximum IN (inward) focuser
coordinate. Recommended for
Crayford and rack-and-pinion
focusers found in most refractor and
reflector telescopes.
