 Stack of 16 images:
- Images adjusted in Lr, exported as 16-bit TIFFs
- Imported to Ps as a stack (no auto alignment)
- Images 2 through 16 rotated -0.025 degree per step (e.g. image 5 was rotated -0.1 degree) to account for sky rotation
- Images manually shifted into alignment
- Images 2-16 adjusted opacity to 1/image#, e.g. image 4 at 1/4 = 25%
- Cropped to eliminate non-overlapping image areas
- Image adjustment (selective curves, sharpening)
- Reduce to 8-bit
- saved as JPEG

Note: The trees at the lower extremity were stacked separately with no shift or rotation, and combined with the sky image.
All images shot at ISO 6400 with no NR. No NR applied during Lightroom conversion or subsequent Ps processing.
