In this tutorial, James Ritson offers a comprehensive guide to monochrome astrophotography using Affinity Photo V2. James will show you how to stack narrowband data, focusing on H-alpha, sulfur-2, and oxygen-3 images, with adaptability for broadband RGB mono data. He begins by demonstrating how to add light and calibration frames and utilize the File Groups feature for organized processing. James teaches you how to blend and color map data using the classic Hubble Palette and balance the intensity of emission layers with the Linear Fit tool. Additionally, he provides techniques for enhancing images with selective color adjustments, noise reduction, and a final crop for composition.
