Mastering Broadband: A Comprehensive Photoshop Processing Guide
In this three-part tutorial series, Telescope Live tutor Peter Jenkins walks you through the entire process of enhancing the M51 galaxy using only Photoshop (data stacked in a free software - Deep Sky Stacker). Each part focuses on a crucial aspect of the workflow:
Part 1: Stretching and Cropping Basics
-Learn how to stretch, crop, and adjust the levels of the RGB and luminosity images.
-Set up a consistent crop across all image files.
Part 2: Color Balancing and Sharpening
-Fine-tune color balances to match the RGB channels.
-Apply sharpening techniques and use a layer mask for selective sharpening.
Part 3: Integrating Luminosity and Final Adjustments
-Integrate the luminosity layer to enhance detail.
-Perform advanced color corrections and final adjustments to bring out the galaxy's intricate details.
This series will equip you with the workflow to process any galaxy using Photoshop alone, however, this tutorial will also give you the necessary tools to process any other broadband dataset with ease.
Replicating Deconvolution in Affinity Photo: Sharpening Techniques with Nik Szymanek
In this tutorial, Telescope Live tutor Nik Szymanek explores the powerful sharpening tools available in Affinity Photo to enhance astronomical images. While Affinity Photo lacks true deconvolution capabilities, Nik will demonstrate how to use the Unsharp Mask, High Pass, and Clarity filters to simulate convolution and improve image sharpness effectively. Using a stunning image of the galaxy NGC 5128, he will guide you through each tool's settings, showing how to bring out fine details and contrast. Nik will also explain how to integrate RC Astro's Star Exterminator to remove stars before applying sharpening filters. By combining these techniques, you can achieve impressive results, enhancing details like the jet from the galaxy's nucleus and the star shells from a galactic collision.
Salvaging Images with Pixel Math: Warren Keller's Emergency Flats Technique
In this tutorial, Telescope Live tutor and Masters of Pixinsight presents a creative solution for recovering astrophotography images lacking flat field calibration. When faced with dust motes and other issues, Warren demonstrates using Pixel Math in PixInsight to apply a different master flat to a master light after initial calibration. Through a specific Pixel Math expression, he shows how to reduce star artefacts and correct gradients, turning an unusable image into a viable one. Warren’s method provides a practical tip for handling emergencies in astrophotography processing.
