Fixing Aberrations and Star Shapes in PixInsight

3
In this two-part series, Alex Curry delves into the challenges of wide field of view imaging and its impact on your astro images. He'll introduce you to some traditional techniques for rectifying these issues, applicable across various astrophotography editing software. In Part 2, Alex focuses on a novel PixInsight plugin designed for smart image correction and feature sharpening. He'll guide you through the necessary prerequisites and adjustments to optimize the plugin for your specific data.

Where did you get the number 3.18 that you entered into PSF Diameter in BlurXTerminator. You said you captured it. How and where?

Worth noting that for Macintosh with Apple Silicon GPU acceleration is built in to the OS. This makes BXT amazingly fast. BXT is effectively mandatory for the TL TAKs and as you showed greatly improves the images.
