Ultimate Reflection Nebula Processing on PixInsight

6
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.

Thank you for a very informational tutorial! Only one question--when you are in real time previews, you seem to be able to drag a preview window to zoom in on a particular area, which I don't seem to be able to do (but I'm using a Mac, so maybe that's the issue?). Is there some special thing you need to do to make this doable?

A really helpful set of tutorials .. however "Part 2" seems to be lacking any sound . Am I doing something wrong?

This is an amazing resource you've put together for us, Warren, thanks a lot.

Quick question, in the video you refer to your process icons (which we can see on the right). I've done a quick Google search and can see a set published dated July 2022 (on theastroimagingchannel), which doesn't quite match the latest and greatest (from RC-Astro, and others) tools and PixelMath expressions.

Is it possible to share your latest process icons set with us here at TL? I know we can probably 'rebuild' it from the screen (minus your recommended values), but would really appreciate it if you were to share yours. Thanks.
