Description

This is from six 10-minute observations made between 2014 and 2015 in varying conditions.

Processing focused on reducing noise while maintaining detail. I used MaxIM DL stacking with Sigma Clip to manage brightness, then used tools like DDP, FFT Filters and curves adjustments. In Photoshop I used tools like Google's Nik collection Dfine 2, Astronomy Tools Deep Space Noise Reduction, along with Curves, Hue/Saturation and Color Balance; I also did some manual editing on pixels throughout.
