Orion revisited with Pixinsight

This is a rework of my data from Dec 30 using Nebulosity for stacking, PixInsight for the the heavy lifting, and final tweaks in Photoshop. This was a reminder of the differences in processing DSOs from planetary data for me. PixInsight made short work of the light pollution in these images tanken under brigh suburban skies in Austin.

Sony a7 iii camera with a William Optics RedCat 250/52mm telescope, Astromania Moon and Skyglow filter, on a Vixen Polarie Mount. Bortle 6 sky under the light dome of Austin, Texas. Exposure stack of almost 2 hours of data: Thirty second exposure ISO 640 (yes 640, to maximize dynamic range) with 228 images stacked in Nebulosity. Postprocessed to remove sky glow gradient and color correct for the sky glow filter in Nebulosity. Final crop, exposure adjustments, and touch up in Photoshop.
