In this final part of the NGC 6744 tutorial, Telescope Live tutor Nik Szymanek completes the image processing workflow by applying cosmetic corrections and color refinements in Affinity Photo. Key steps include: Combining Luminance and RGB for LRGB Processing: - Convert the luminance image to a 16-bit RGB file and merge it with the RGB image for enhanced detail. - Flatten the image and export it as a high-quality TIFF file. Gradient Removal and Star Integration: - Extract stars using PixInsight’s Star Exterminator and process them separately. - Use Graxpert AI for automatic background gradient removal before reintroducing stars. Final Color and Detail Enhancements: - Apply Tone Mapping for subtle contrast boosts in the galaxy without affecting the background. - Use Selective Color and Clarity tools to refine spiral arm structures and highlight Hα regions. This final stage brings out the full depth and color of NGC 6744, wrapping up a comprehensive multi-software workflow.

In this follow-up to the stacking multi-camera data tutorial of NGC 6744, Telescope Live tutor Nik Szymanek expands on the dataset integration process, moving from Astro Pixel Processor (APP) to PixInsight for advanced image refinement. Key steps include: Finalizing Stacking and RGB Combination in APP: - Integrate all CCD and CMOS frames to produce high-quality LRGB masters. - Use Multiband Blending (MBB) to seamlessly merge different datasets. Processing in PixInsight: - Crop Luminance and RGB images to a uniform size using Dynamic Crop. - Apply BlurXTerminator to enhance detail through deconvolution. - Use Gradient Correction to remove residual sky gradients. Noise Reduction and Image Scaling: - Utilize NoiseXTerminator AI3 for effective noise suppression with real-time previews. - Adjust histogram settings to control brightness and preserve background details. This tutorial sets the stage for the final enhancements in Affinity Photo, covered in the next tutorial.
