Settings

The Settings tab is the first tab you should visit after you connect all of your equipment to set various settings that affect many aspects of N.I.N.A.. You will find a lot of various settings to adjust here.

General Settings

The General Settings tab allows you to manage N.I.N.A. in terms of all general settings. Settings here affect the whole application.

Settings: General

      > This action cannot be reversed, so pay attention to what you delete!
  3. Load profile
    • Loads the currently selected profile
  4. Language Drop Down
    • Allows you to change the language of N.I.N.A.

Equipment Settings

This tab allows you to change settings related to your equipment.

Settings: Equipment
  1. Camera Pixel Size
    • The Pixel Size of your camera sensor in micrometers

  7. Raw converter
    • You can change the raw converter here
    • Only applies to DSLR
    • Available converters: DCRaw and FreeImage
      • DCRaw will utilize DCRaw and stretch your images to 16bit, applying the cameras specific color bias profile
      • FreeImage will deliver the frame exactly as your camera provided it and can be slightly faster for image download on slower machines
        > Note that both raw converters will deliver you the raw frame of your DSLR. but they might vary in color. Saving the raw frame without adding the camera specific profile with FreeImage can deliver more faint and less colorful raw images than you are used to.
  8. Telescope Focal Length
    • Enter your telescope focal length here
      > This will be used for plate solving

  13. Add or Remove to/from Filter List
    • Manually add or remove filters from the filter list
      > Removing always removes the selected filter
  14. Import Filters from Filter Wheel
    > You should run this once to synchronize your filters from ASCOM to N.I.N.A.
  15. PHD2 Server URL and Port
    • You can set the PHD2 server settings here
      > Usually the defaults should work fine
      > You need to enable PHD2 server in PHD2

  17. Dither RA Only
    • Enables dithering in the RA axis only

Imaging Settings

In the Imaging settings you can find various imaging related settings like file name patterns and display options for the imaging tab.

Settings: Imaging

    • TIFF can be left as default
      > To save space you can use TIFF (Zip) or TIFF (LZW)
      > – Both algorithms are slower to save a file
      > – Compression ratio may vary and you want to test out both algorithms
  2. Image File Path
    • The file path where you want to store the saved images
      > Please note you need to use “\\” instead of a single “\” for folder separation
  3. Image File Pattern Preview
    • This button shows you a preview of the file pattern as defined in (4)
  4. Image File Pattern
    • Here you can define the file name pattern based on the variables in (5)

      > This setting will affect the plate solver!
  12. Annotate images
    • When enabled will annotate the images with HFR of the detected stars
    • Only will annotate them when HFR detection is active
