Script commands for sequences
Posted: 18 May 2023, 15:15
Astroart 8 SP4 has some new script functions to create a sequence of images. Try the following example after having connected the Camera Simulator:
A real sequence will probably need to save its images, so for example the command "Autosave(false)" could be replaced with: (See below the command "Autosave")
Sequencer.Autosave("NGC_4564", "D:\AstroData\2023-05-11\")
In the example, the sequence is built at run-time with the commands "Add", but it's also possible to open it from the disk with the command "Open".
The command "WaitAll" could be replaced by a cycle with the command "WaitOne", for example:
The list of functions is:
Sequencer.Clear
Resets the sequence and reset the "New window" option.
Sequencer.Add(filter, count, exposure, binning, [focuser])
Adds a row, to build a sequence at run-time, example: Sequencer.Add("R", 10, 60, 2, "AF")
Sequencer.Open(filename)
Opens a sequence from disk, by default from the Sequence Folder, example: Sequencer.Open("LRGB-10-60").
Sequencer.Start
Starts the sequence.
Sequencer.Active
Returns the status of the sequencer, as a boolean value.
Sequencer.WaitAll
Waits until the whole sequence is complete.
Sequencer.WaitOne
Waits for a single exposure.
Sequencer.Index
Returns the index of the current exposure.
Sequencer.Autosave(enable) , Sequencer.Autosave(filename, [folder])
Enables or disables the automatic saving of images and sets the filename and the folder.
Sequencer.Repeat(n)
Sets the "Repeat" option of the sequence.
Sequencer.NewWindow(enable)
Sets the "New Window" option of the sequence, which must NOT be enabled for long sequences. For this reason the option is automatically disabled by the commands "Clear" and "Open".
-------------------------------------------
Until now, sequences had to be coded explicitly, this is still more flexible if you are a programmer. For example:
Code: Select all
if Sequencer.Active then
print "Sequencer already running"
Script.Stop
end if
Sequencer.Clear
Sequencer.Add("Light", 3, 10, 1)
Sequencer.Add("Dark", 2, 10, 1)
Sequencer.Autosave(false)
Sequencer.Start
Sequencer.WaitAll
Sequencer.Autosave("NGC_4564", "D:\AstroData\2023-05-11\")
In the example, the sequence is built at run-time with the commands "Add", but it's also possible to open it from the disk with the command "Open".
The command "WaitAll" could be replaced by a cycle with the command "WaitOne", for example:
Code: Select all
while Sequencer.Active
Sequencer.WaitOne
print "Image #" ; Sequencer.Index
end whileSequencer.Clear
Resets the sequence and reset the "New window" option.
Sequencer.Add(filter, count, exposure, binning, [focuser])
Adds a row, to build a sequence at run-time, example: Sequencer.Add("R", 10, 60, 2, "AF")
Sequencer.Open(filename)
Opens a sequence from disk, by default from the Sequence Folder, example: Sequencer.Open("LRGB-10-60").
Sequencer.Start
Starts the sequence.
Sequencer.Active
Returns the status of the sequencer, as a boolean value.
Sequencer.WaitAll
Waits until the whole sequence is complete.
Sequencer.WaitOne
Waits for a single exposure.
Sequencer.Index
Returns the index of the current exposure.
Sequencer.Autosave(enable) , Sequencer.Autosave(filename, [folder])
Enables or disables the automatic saving of images and sets the filename and the folder.
Sequencer.Repeat(n)
Sets the "Repeat" option of the sequence.
Sequencer.NewWindow(enable)
Sets the "New Window" option of the sequence, which must NOT be enabled for long sequences. For this reason the option is automatically disabled by the commands "Clear" and "Open".

Until now, sequences had to be coded explicitly, this is still more flexible if you are a programmer. For example:
Code: Select all
Sequ(10, 60.0, 2, "R")
Sequ(10, 60.0, 2, "G")
Sequ(10, 60.0, 2, "B")
Sequ(10, 60.0, 1, "L")
end
sub Sequ(images,exposure,binning,filter)
Camera.Binning(binning)
if filter <> "" then
Wheel.Goto(filter)
Wheel.Wait
end if
for i = 1 to images
Camera.Start(exposure)
Camera.Wait
fileName = object + filter + Format(i,"000") + ".fit"
Image.Save(dir + fileName)
Image.ClosePrevious
print dir + fileName
next i
end sub
