The Great Andromeda Galaxy.
241x45" exposures, combination of Backyard and Spruce Knob data from earlier this year.
3hr 21m18s total exposure time.
Slight crop, composite image.

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
