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
