Advanced setting



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.
