This complete intermediate Siril master class by Telescope Live Co-Founder Alexander Curry pushes Siril to its processing limit providing you with a comprehensive workflow for any nebula dataset. Across 6 episodes, Alex will guide you through all the techniques you would need to process a nebula dataset, focusing on a small 1hr dataset of the Seagull nebula, Alex will cover the following workflow: Data Preparation and Stacking - Satellite trail removal with Cosmic Clarity - Data organisation and stacking with Telescope Live Siril scripts Deconvolution with Cosmic Clarity - Again using the Cosmic Clarity suite for a free “deconvolution” and sharpening tool - Use your calculated PSF values for appropriate sharpening factors Colour Calibration and De-Linearisation - Plate solving and photometric colour calibration - Histogram adjustments for first de-linearisation Starless Workflow - Star reduction using StarNet++ - Adjustment to star layers for colour clarity and halo reduction - Subsequent luminance preparation Colour Adjustments and Luminance - Starless colour adjustments and balancing - Optional (for HaRGB) Ha enhancement workflow - Luminance integration Denoise and Finishing Touches - Denoising with Cosmic Clarity/GraXpert - Star layer re-compositing

In this six part hybrid processing tutorial, Telescope Live tutor Peter Jenkins, demonstrates the step-by-step workflow for processing an image of the Eagle Nebula (M16) using both PixInsight and Photoshop. Key steps covered include: Data Preparation in PixInsight: - Learn how to register, align, and crop Hydrogen Alpha, Oxygen III, and Sulfur II data using PixInsight’s dynamic crop tool. - Use powerful tools like Blur Exterminator and Noise Exterminator to enhance image clarity and reduce noise before going non-linear. Star Processing and Channel Combination: - Explore how to handle star removal with Star Exterminator and create color-matched stars from Hydrogen and Oxygen data. - Combine the data into the Hubble Palette and adjust the color balance using Narrowband Normalization and SCNR processes. Final Enhancements in Photoshop: - Discover Peter’s preferred method for fine-tuning color and sharpening nebula details, while reintegrating stars in Photoshop.
