      In this webinar, Nik Szymanek demonstrated a comprehensive post-processing workflow using the NGC 3293 Observation Bundle from Telescope Live. Leveraging the capabilities of multiple tools, including PixInsight, Affinity Photo, and the suite of XTerminator plugins (Blur, Star, and Noise XTerminator by RC Astro) Nik showed participants a unique glimpse into his process that frequently yields remarkable results.

      The journey begins in PixInsight, where an RGB FITS image is created and subsequently scaled alongside the H-alpha integration. Deconvolution is run using the BlurXTerminator plugin, and after some histogram transformations, the mono and RGB frames are combined into a pseudo 'LRGB' image, an Ha-SHO format that takes advantage of the high signal-to-noise ratio of the H-alpha data, utilizing it as a luminance frame.

      The stars are then extracted using StarXTerminator in PixInsight, creating a starless and a star-only version of the image. These are then further enhanced in Affinity Photo, using the Tone Mapping tool on the starless layer and color manipulation via Selective Colour. After noise reduction with NoiseXTerminator, the image is further refined with adjustments such as sharpening and scaling.
