Salvaging Images with Pixel Math: Warren Keller's Emergency Flats Technique
In this tutorial, Telescope Live tutor and Masters of Pixinsight presents a creative solution for recovering astrophotography images lacking flat field calibration. When faced with dust motes and other issues, Warren demonstrates using Pixel Math in PixInsight to apply a different master flat to a master light after initial calibration. Through a specific Pixel Math expression, he shows how to reduce star artefacts and correct gradients, turning an unusable image into a viable one. Warren’s method provides a practical tip for handling emergencies in astrophotography processing.
