AutoIntegrate v1.72 - Ha to RGB mapping, true background

PixInsight repository for AutoIntegrate is https://ruuth.xyz/autointegrate/.

A fix release v1.72.1 fixes the following problem:

  • Removed a call to physicalMemoryStatus. It is only available in PixInsight 1.8.9-3 or later.

Changes in this version v1.72 are listed below.

Ha to RGB mapping

  • Many updates to Ha to RGB mapping. Works better in most cases.
  • Ha to RGB mapping noise reduction is now done after continuum subtraction and it is enabled by default.
  • Added a new Continuum boost option.

Find true background

  • Added a method to find a true background area in an image that is used by the BackgroundNeutralization process.
  • It is enabled by default but can be switched off with the “No auto background” option.
  • A new image named AutoBackgroundModel is created that shows the background area. The AutoBackgroundModel can be edited and it is used with AutoContinue if it already exists.

Noise reduction changes

  • Combined image noise reduction renamed to Processed linear image. It more correctly describes the phase when noise reduction is done.
  • New noise reduction option Integrated image. It is done for combined RGB or color/OSC image before any other processing.

Save processed channel images

  • A new option “Save processed channel images” was added.
  • For mono RGB images, channel images are saved before channel combination.
  • For mono narrowband images, channel images are saved before RGB mapping.

Save stretched starless channel images

  • A new option “Save stretched starless channel images” is added.
  • Images are saved as .xisf and .tif files.
  • These channel images can be used for example for color mapping in Photoshop. For a great example see Utah Desert Remote Observatories YouTube channel.
  • For mono RGB images, channel images are saved before channel combination. For mono narrowband images, channel images are saved before RGB mapping. For OSC/color images, channel images are extracted and saved before stretching.
  • A new option “Auto contrast on channel images” runs auto contrast on stretched channel images.
  • When using this options is is often useful to select “Gradient correction on channel images” in “Settings” tab, noise reduction on “Channel image” in “Processing 1” tab and BlurXTerminator option “Correct only on channel images” in “Processing 1” tab.

Other new options

  • Added an option to choose when color calibration is done.
  • A new option “Correct only on channel images” to run BlurXTerminator in correct only mode on channel images.

Other

  • Updates to comet processing workflow text.
  • Removed predefined telescope info for image solving. It did not always work.
  • Fixes to AutoContinue with separate autocontinue prefix.
  • For color/OSC data, Gradient correction on channel images now does the same as Gradient correction on combined images.
  • Flowchart and file close optimizations.
  • Fix to error “ReferenceError: physical memorystatus is not defined”. when using PixInsight 1.8.9-2 or older.
    -Back to build in Telescope Live telescopes. If default image solving fails, script tries with predefined settings.
  • Added option to set pixel combination operation for ImageIntegration
  • Limited iterative stretch from 100 to 20 steps.
  • Updated experimental Asinh+Histogram stretch to use build in ArcsinhStretch and the histogram stretch.
