Settings
You can change lots of settings by going to the Settings, Process, and/or Mechanics
setting pages.
The Settings page has the following options:
·
Auto Select Star : Automatically detect and select best star for guiding in the image.
·
Subframe : Subframe around the focus star during the autofocus procedure. Enabling
subframing can significantly speed up the focus process.
·
Full field : Measure average HFR from all stars combined in a full frame. This method
defaults to the Centroid detection, but can use SEP detection too. Its performance
decreases as the number of stars increases.
·
Suspend Guiding : Suspend Guiding while autofocus in progress. If the focus process
can disrupt the guide star (e.g. when using Integrated Guide Port IGP whereas the
guider is physically attached to the primary CCD), then it is recommended to enable
this option. When using Off-Axis guider, then this option is not necessary.
·
Dark Frame : Check this option to capture a dark frame if necessary and perform dark-
frame subtraction. This option can be useful in noisy images.
·
Box : Sets the box size used to enclose the focus star. Increase if you have very large
stars.
·
Annulus : During full field focusing, stars which are inside this percentage of the frame
are filtered out of HFR calculation (default 0%). Detection algorithms may also have an
inherent filter.
·
Settle : Sets the amount of seconds to wait before resuming guiding.
