Wavefront Restore Documentation

Wavefront Restore, WFR for short, is a PixInsight process for blind deconvolution. It reads from your stars what your telescope, mount and sky did to the image (defocus and field curvature, spherical aberration, coma, astigmatism, trefoil, chromatic aberration, and elongation from guiding errors, wind or the mount) and reverses it across the whole image, stars and everything else alike. It can also remove blur from atmospheric seeing, usually the biggest blur in the image. It needs no measured point spread function.

Where to Start

Section titled “Where to Start”
  1. Install it from the Wavefront Restore repository.
  2. Activate it with the email address and license code from your invitation.
  3. Learn the process window: How to Use Wavefront Restore.
  4. Read How It Works, including why it needs linear data.
  5. Choose a mode: Correct aberrations or Deblur and recover detail.

Requirements

Section titled “Requirements”
  • PixInsight 1.9.5 or later.
  • Windows 10 or later, or macOS Sonoma (14.0) or later on Apple silicon. Linux support is coming soon.
  • For full-size images, an NVIDIA graphics card on Windows; on a Mac, Apple silicon does the work. Without one, Wavefront Restore falls back to the CPU, which is very slow on large images.
  • On a Mac, 8 GB of memory for images up to about 62 megapixels, 16 GB for about 100 megapixels. Windows figures are still being measured; see the FAQ.
  • Linear images, before any stretch.
  • A beta license: the email address and license code from your invitation. The beta is free and by invitation; see The Beta.
  • An internet connection the first time you use it on each computer, and at least once every 30 days after that.
