AutoIntegrate Narrowband Combinations Tool

AutoIntegrate Narrowband Combinations Tool

1. Overview

This script is a specialized tool designed to blend individual monochrome narrowband images (such as H-alpha, O-III, and S-II) into a single color (RGB) image. It serves as a standalone version of the combination engine found in the AutoIntegrate script, allowing you to mix channels using standard palettes (like the Hubble Palette) or custom formulas without running a full processing pipeline.

Note! This is a test version available in the test repository.

2. Inputs & Parameters

To use this tool, your grayscale images must already be opened in PixInsight.

  • Channel Selection: You must map your open windows to the script’s channels.
    • H-alpha / S-II / O-III: Select the corresponding open image for each channel from the dropdown lists.
  • Palette: Choose a predefined color mapping strategy from the dropdown menu.
    • Examples include SHO (Hubble Palette), HOO (Bi-color), or HOS. This determines which gas maps to Red, Green, and Blue.
  • PixelMath Formulas (R/G/B): (Optional) The script automatically populates these based on your chosen Palette. You can manually edit these blending formulas to fine-tune how much of each input channels goes into a specific color channel (e.g., 0.8*H + 0.2*O).
  • Update Preview button: The preview window is updated with the Update Preview button. To generate the final image you need to press the Process Final button. The Process Final button generates the final image from the preview image.
  • Preview autostretch: Since channel images are usually non-stretched (linear) the preview image is stretched for user convenience. Stretching can be disabled by unchecking the AutoSTF option.

3. Output

  • A new Image: The script generates a new window from the preview image with the Process Final button.The output is typically a linear (unstretched) image, preserving the data for further processing (like background extraction or noise reduction).
