release button.

When shooting is finished, the
ASTROTRACER setting screen is
displayed again.
• When using the ASTROTRACER function, the
shutter cannot be released and shooting will not
start until the GPS positioning is carried out.
• The maximum trace duration varies depending
on the focal length, shooting location, or
direction that the camera faces to. You cannot
set the exposure time longer than the maximum
trace duration.
• When using a lens without focal length
information, set the focal length of your lens with
[Input Focal Length] in the [A Rec. Mode] menu
before shooting images of astronomical objects.
• Always execute the precise calibration before
shooting images of astronomical objects.
• When using the ASTROTRACER function,
[Horizon Correction] and [Composition Adjust.]
of the camera are not enabled.
• As the precise calibration performs high-
accuracy calibration, it takes a while to
complete.
• When shooting images of astronomical objects,
you cannot use autofocus. Adjust the focus
manually.
