In this tutorial, award-winning solar astrophotographer Mark Johnston guides you through the steps he took to create his NASA APOD-winning image of a solar sunspot with a light bridge. This tutorial will detail the specific steps Mark Johnston used to transform his solar data into an award-winning image. Mark will discuss three important pieces of software required for this achievement: ImPPG, Affinity Photo, and Topaz Denoise. DISCLAIMER: Understanding the background of solar post-processing is crucial before attempting a more advanced tutorial like this. We offer a comprehensive guide to solar post-processing, including the necessary background information you need before starting. Look for the tutorial named “SOLAR IMAGE EDITING PRIMER”

In this two-part tutorial by Alexander Curry, he discusses the use of plate solving to calculate the field of view and target location based on the geometrical relationship between the stars within the image. Following this, Alex demonstrates how to use photometric color calibration (PCC) to correct the color balance of your image using the results from plate solving. Part 1 of this tutorial covers the introduction to plate solving and configuring Siril with the star catalog files required for plate solving and PCC. Part 2 discusses setting up plate solving necessary for running PCC. This section also explores various methods for determining the astrometric solution for your image, should you be solving "blind."

In this workshop hosted by Masters of PixInsight for their subscribers, TL tutor and MoP founder Warren Keller presents a crash course on initiating post-processing for a reflection nebula in PixInsight. This session was a live demonstration for Masters of Pixinsight members. Warren covers various methods for initial de-linearization stretches and their comparisons. He also explores the roles of BlurXTerminator and NoiseXTerminator in the post-processing workflow. The session concludes with Warren providing tips for advancing further in post-processing.

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. - Advance into Siril’s post-processing features: color calibration, star subtraction in L and RGB images, luminance integration, saturation tweaks, and detail enhancement through denoising and sharpening. - These two parts culminate in a complete, refined image using solely Siril, making it accessible for those preferring or limited to free software. Part 3: Enhanced Finishing with Affinity Photo - For those seeking to elevate their image further, this part shifts to Affinity Photo. - Focus on advanced retouching techniques, including revisiting Siril’s output for final touches. - Topics include luminance integration, intricate color work, saturation balance, sharp image sharpening, star overlay, and effective noise reduction. Alex’s expert guidance ensures a thorough learning experience, from building a solid foundation with Siril to applying the finishing professional touches with Affinity Photo.
