Release Note

  • TopK issue patch

Do you need any help?

If you have any issues or have questions about this model or the Siril's script, please open an issue in this repository.
For common issues that may arise I am going to keep updated this page for fixes.

  • Computers with Intel Ultra may face issues running this model.

How to use

This model has to be used in conjunction with a script. I officially support AberrationRemover script in Siril, but SetiAstro provides one for SASpro. In Siril the script has to be downloaded by going in the top bar > scripts > get scripts > AberrationRemover.

This model is intended for linear images after background removal and color correction.
For best results, apply it before any deconvolution or noise reduction steps.

Starting from version 1.1.0 of Siril's script, new parameters are available:

  • strength: controls the intensity of the aberration correction.
  • Dark ringing reduction: applies an additional filter to suppress dark ringing artefacts that may appear around bright stars as a side effect of strong correction. This option should be enabled only if such artefacts are visible.
  • Protect Background: limits the application of AR to non-background pixels, preventing over-processing in low-signal areas.

‼️ In normal conditions, you should not need to adjust these parameters. If manual tuning is required, please consider it a potential issue and report it. For now, Siril is the only officially supported platform by me.

What does this do?

Aberration Remover (AR) is an AI-based tool designed to remove optical aberrations from images, affecting both stellar and non-stellar components. It can correct monochromatic aberrations such as defocus, astigmatism, coma, trefoil, spherical aberration, and other higher-order aberrations.

AR is not designed to correct sensor or optical tilt, lateral chromatic aberration, or to compensate for atmospheric seeing.
