Sequence

With Sequences you are able to create imaging sequences with various options for automation. The main usage is to set exposure times, filters and other settings for a total amount of frames to not have to shoot manually and have it stop after a specific amount of frames.

For further information about sequencing refer to Usage: Advanced Sequencing and Usage: Automated Meridian Flip.

Tab: Sequence
  1. Delay start
    • Allows you to delay the start of the sequence by a specific amount of seconds
  2. Sequence Mode
    • You can change the sequence mode from “One by another” to “Rotate through”
      • “One by another” would process each sequence entry (10) fully before switching to the next sequence entry
      • “Rotate through” would process one item from a sequence entry and then continue with the next. Allows for example the rotation of LRGB sequences.
  3. Start guiding
    • When enabled will try to start guiding with PHD2 after the start of the sequence
    • PHD2 needs to be connected in the PHD2 Tab
  4. Slew to target
    • Slews to the target as specified in RA and Dec
    • Does not Plate Solve to verify it is on target
  5. Center target
    • Will center the target given the Ra and Dec coordinates
    • Utilizes the plate solver as specified in the settings
      > Requires a set up primary plate solver
  6. Estimated Download Time
    • You can enter the approximate download time your camera takes to download a single image
      > Will be automatically populated with the average download times as measured by N.I.N.A. on image download
      > Will be added to calculations of (9)
  7. Estimated Finish Time
    • Shows you the estimated finish time when your sequence will end
    • Adds the download time (8) to each sequence entry
      > Needs to be manually refreshed using the button on the right of the estimation
  8. Auto Focus Expander
    • Will show all enabled auto focus options when not expanded
      > All settings inside require a connected auto focuser
  9. Auto focus on start
    • Starts the auto focuser sequence to pinpoint the automatic focus
  10. Auto focus on filter change
    • Starts the auto focus routine for every switch of the filter wheel
  11. Auto focus after elapsed time
    • Starts the auto focus routine after a set amount of time has passed since the last auto focus routine
  12. Time that has to pass
    • Specifies the time in minutes that have to pass to trigger the auto focus routine
  13. Auto focus after a number of exposures
    • Starts the auto focus routine after a set amount of exposures have been taken since the last auto focus routine
  14. Amount of exposures
    • Specifies the number of exposures that have to be taken to trigger the auto focus routine
  15. Auto focus after a temperature change
    • Starts the auto focus routine after a set amount of temperature change
  16. Amount of temperature change
    • Specifies the temperature difference that has to be reached after the last auto focus routine
      > Requires a temperature sensor that reports the temperature for the auto focuser
  17. Sequence entry
    • Each sequence entry consists out of up to 9 columns which determine how the image will be shot
      • Progress: shows the current progress of the image sequence
      • Total #: the amount of frames for that specific sequence entry
      • Time: the exposure time in seconds
      • Type: the type of the sequence entry: BIAS, DARK, LIGHT, FLAT. Takes into effect only on the naming of the file pattern
      • Filter: the filter that should be used
      • Binning: the binning of your camera that should be used
      • Dither: enable it if this sequence entry should dither while downloading
        > Dithering will only work when PHD2 is connected
      • Dither Every # Frame: will dither only every # frame as set when dithering is enabled
      • Gain: Change the gain of the camera for this entry. Only available when camera can set gain
    • Sequences cannot be changed while the sequence is running, you need to pause, abort it or wait until it’s finished to change the amount of frames
  18. Add new Sequence entry
    • Adds a new sequence entry line
  19. Delete Sequence entry
    • Deletes the currently selected sequence line
  20. Save Sequence
    • Allows you to save the sequence as a .xml file
  21. Open Sequence
    • Allows to load a previously saved sequence file.
    • Will overwrite all current sequence settings
  22. Start Sequence
    • Starts the sequence
    • Once started morphs into two buttons which allow you to pause or cancel the sequence
      • Pausing will pause the sequence after the current frame
      • Cancel will abort the frame capture completely and stop the sequence
  23. Target information
    • Shows you the target name, RA and Dec
    • Can be changed from here
    • RA and Dec will affect slew on start (4) and center target (6)
  24. Object altitude
    • Shows the objects altitude, what direction it will transit and the darkness phase of today, including the current time
      > Altitude depends on Latitude and Longitude set in the Settings
