Slight crop, composite image.

E

2x Drizzle edit, cropped. Added some more frames from my backyard for this stack, 1hr 7m exposure time (mixture of iso 400 and 800 subs, 45 sec subs).

F

3hr21m18s Exposure time, 50-sec exposures. Used Pixinsight for ABE, channel extraction and ACDNR/curve adjustment on the individual channels, then recombination and color calibration. Photoshop for layer blending and saturation boost. Lightroom for sharpening, removed the purple and red halos with CA removal tool, and noise reduction. Slightly downsampled and saved as .jpeg
