again will place the focus frame back into the docked position.
· Show in FITS Viewer: Shows the focus frame image in FITS Viewer.
· Bin: Specify horizontal (X) and vertical (Y) binning.
· Gain: Specify the value of gain between 0% to 100%. This will increase the
signal to noise level of your image.
· ISO: For DSLR cameras, specify the ISO value.
· FW: Select the active Filter Wheel device. If your camera has a built-in filter
wheel, the device would be the same as the camera.
· Filter: Specify desired filter.
· Filter Settings: Use the Filter Manager to specify various settings for each filter
including exposure, offset, autofocus, and locking policy. Settings

You may need to adjust focus settings in order to achieve a successful and
reliable autofocus process. The settings are retained between sessions.
· Auto Star Select: Automatically select the best focus star from 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.
