Field notes
Nebula Stacker presents astrophotography stacking as an auditable sequence rather than a single opaque output. Its described pipeline includes eight phases, preserves the sensor mosaic until final demosaicing, and uses Gaia star colours for colour calibration. The site also says users can inspect a night’s frames, plate-solve them, and compare a sub with the resulting stack before paying for the stacking function.
