Calibration Settings
Note : You can only edit calibration settings for capture jobs that have the frame type as
Bias (B), Dark (D), or Flat (F).
For Flat Field frames, you can set calibration options in order to automate the process. The
calibration options are designed to facilitate automatic unattended flat field frame capture.
It can also be used for dark and bias frames if desired. If your camera is equipped with a
mechanical shutter, then it is not necessary to set calibration settings unless you want to
close the dust cover to ensure no light at all passes through the optical tube. For flat fields,
you must specify the flat field light source, and then specify the duration of the flat field
frame. The duration can be either manual, or based on ADU calculations.
1.
Flat Field Source
o
Manual : The flat light source is manual.
o
Dust Cover with Built-In Flat Light : If using a dust cover with built-in light
source (e.g. FlipFlat). For dark and bias frames, close the dust cap before
proceeding. For flat frames, close the dust cap and turn on the light source.
o
Dust Cover with External Flat Light : If using a dust cover with external flat
light source. For dark and bias frames, close the dust cap before proceeding.
For flat frames, open the dust cap and turn on the light source. The external flat
light source location is presumed to be the parking location.
o
Wall : Light source is a panel on the observatory wall. Specify the Azimuth and
Altitude coordinates of the panel and the mount shall slew there before capturing
the flat field frames. If the light panel is controllable from INDI, Ekos shall turn it
on/off as required.
2.
Flat Field Duration
o
Manual : Duration is as specified in the Sequence Queue.
o
ADU : Duration is variable until specified ADU is met.
