Before the calibration capture process is started, you can request Ekos to park the mount
and/or dome. Depending on your flat source selection above, Ekos will use the appropiate
flat light source before starting flat frames capture. If ADU is specified, Ekos begins by
capturing a couple of preview images to establish the curve required to achieve the
desired ADU count. Once an appropiate value is calculated, another capture is taken and
ADU is recounted until a satisfactory value is achived.
Limit Settings
Limit settings are applicable to all the images in the sequence queue. When a limit is
exceeded, Ekos shall command the appropiate action to remedy the situation as explained
below.
·
Guiding Deviation : If checked, it enforces a limit of maximum allowable guiding
deviation for the exposure, if autoguiding is used. If the guiding deviation exceeds this
limit in arcseconds, it aborts the exposure sequence. It will automatically resume the
exposure sequence again once the guiding deviation goes below this limit.
·
Autofocus if HFR exceeds a value : If autofocus is enabled in the focus module and
at least one autofocus operation was completed successfully, you can set the maximum
acceptable HFR value. If this option is enabled then between consecutive exposures,
the HFR value is recalculated, and if found to exceed the maximum acceptable HFR
value, then an autofocus operation is automatically triggered. If the autofocus operation
is completed successfully, the sequence queue resumes, otherwise the job is aborted.
·
Autofocus if change in temperature exceeds a value : If autofocus is enabled in the
focus module and at least one autofocus operation was completed successfully, you
can set the maximum acceptable change in temperature value. If this option is enabled
then between consecutive exposures, the change in temperature value is recalculated,
and if found to exceed the maximum acceptable change in temperature value, then an
autofocus operation is automatically triggered. If the autofocus operation is completed
successfully, the sequence queue resumes, otherwise the job is aborted.
·
Refocus every x minutes : you can set your focuser to refocus every x minutes.
