Imaging

The Imaging options tab contains settings for file formats, save directories, Automatic Meridian flips, sequencing and image options.

The imaging options tab

  1. Image Save File Format

  2. Image File Path

    • The file path where images will be saved
  3. Image File Pattern

    • The structure of folders and the filename can be defined by the user using the keywords listed below in (5)

      Fixed text is also possible

  4. Image File Pattern Preview

    • This button displays a preview of the user defined file pattern in (3)
  5. Image File Pattern Keywords List

  6. Meridian Flip Enabled

    • This switch toggles the automatic meridian flip
    • The sequence will check between exposures when to start the flip sequence
    • For usage of the automated meridian flip refer to Advanced Topics: Automated Meridian Flip
  7. Minutes after Meridian

    • This defines the amount of time in minutes for the flip sequence to wait once the target has passed the meridian
  8. Use Telescope Side of Pier

    • Some telescope mounts can tell N.I.N.A which side of the pier/tripod the telescope is on which is either west or east
    • If this is enabled, this information is taken into account with the flip sequence logic

      Recommended to have turned off for eqmod users

  9. Recenter after flip

    • When enabled, N.I.N.A. will begin a plate solving sequence after flipping to recenter the target

      Strongly recommended to have this enabled

    Requires a plate solver to be set up

  10. Scope Settle time

    • After flipping the scope, waits for the specified number of seconds to settle the scope

      If you observe trailing in your first platesolve attempts after a flip, increase this value

  11. Pause before meridian

    • The amount of time in minutes until meridian at which the imaging sequence will pause and wait for the meridian to pass as specified in (7)

      I.E. with a value of 5, when a target is 5 minutes away from meridian, the sequence will pause and the flip sequence will wait until it has passed meridian

  12. Autostretch factor and Black Clipping

    • These are the parameters for the display autostretch

      N.I.N.A. uses the same MTF as PixInsight

    Default settings should be very good

  13. Annotate Images

    • When this setting and HFR analysis in imaging is enabled, displayed images will exhibit annotated HFR values on detected stars

      Note that this is only for display in the imaging tab and has no effect on saved data

  14. Debayer Image

    • When a OSC camera is used, enabling this will debayer the images for display purposes

      Images are still saved bayered

  15. Debayered HFR

    • If enabled, images will be debayered first before HFR analysis is done

      This may help with auto focus

  16. Unlinked Stretch

    • When a OSC camera is used, debayering the image generates 3 channels R,G and B
    • By default the autostretch in imaging is linked and may result in unbalanced colour channels
    • Enabling this will enable debayer image, and should result in balanced colour channels when stretching
  17. Star Sensitivity

    • This changes the sensitivity of star detection used for HFR analysis

      The default 'normal' should be sufficient

  18. Noise Reduction

    • This changes the amount of noise reduction performed on the image for star detection and HFR analysis
  19. Sequence Template

    • The user can set a default user defined sequence template here

      Templates can be made with the 'Save template as xml' button in the sequence tab

  20. Park mount when sequence ends

    • Initiates a park once all sequences are complete

      Ascom does not support custom park positions and so the driver must support this For example eqmod's custom park position can override the default park position

  21. Warm camera when sequence ends

    • If the camera driver supports a warming sequence this will be intiated when sequence has ended
  22. Reset Layout

    • This will reset the layout of docked windows in the imaging tab
