In this tutorial series, Telescope Live co-founder Alex Curry guides you through the process of LRGB galaxy processing. Utilizing the free post-processing software Siril for the foundational work and Affinity Photo for advanced retouching, this three-part guide is ideal for beginners looking to harness the full potential of these tools.

Part 1 & 2: Foundation with Siril
- Start with an introduction to the dataset and the processing objectives.
- Learn to set up and stack data in Siril, laying the groundwork for a high-quality image.
