Co-Founder of Masters of PixInsight and Telescope Live Tutor, Warren Keller, presents an exclusive masterclass tailored for processing reflection nebulae. Dive deep into the intricacies of reflection nebula processing, beginning post-image integration, with an exclusive focus on post-processing. The tutorials, categorized under chrominance, luminance, and LRGB processing, provide universal application techniques for reflection nebula imaging. Chrominance sessions delve into background extraction, neutralization, colour calibration, and the integration of third-party plugins for advanced tasks such as deconvolution and denoising, alongside balanced colour calibration and delinearization techniques. Luminance sessions, while following a similar path, emphasize the creative nuances vital for luminance data processing. In the LRGB culmination, Warren elucidates advanced methods from star-colour fine-tuning to overlooked structure enhancements in reflection nebulae and final polishing steps for an impeccable image finish.

Multi-award-winning astrophotographer Bernard Miller has created the perfect formula for a hybrid workflow using PixInsight and Photoshop. In this three-part tutorial, Bernard will show you how he processed two targets, Thor's Helmet and 47 Tucanae, both winning the coveted NASA's Astronomy Picture of the Day award. Part 1 of this series will focus solely on PixInsight, detailing your approach to processing LRGB data within PixInsight along with the processes, scripts, and tools that Bernard used for post-processing an example of M51. This tutorial will begin with the stacked master frames. Part 2 of this series will see Bernard look at the processing of his APOD-winning Thor's Helmet nebula. Following on from the master frames that Bernard processed using the techniques from the previous PixInsight video, he will show you how he takes this monochrome narrowband data and undertakes histogram manipulation, color adjustment, noise reduction, and adds finishing touches. Part 3 of this series looks at the processing of the globular cluster 47 Tucanae. A complicated target for any astrophotographer to post-process, Bernard will show you all the techniques required to process a globular cluster using Photoshop. Along with the techniques that can be applied to LRGB datasets, Bernard will also show you how to properly post-process the stars within the cluster.
