They spin, we spin

My goal is that with each astro picture these get better.

This is a total of 6 minutes: 12 nearly consecutive 30 second exposures.
These 12 were stacked using soft light, saved, and stacked using Screen, and saved.
Then the contrast in the soft light stack was increased, this was multiplied with the screened stack, then the yellow tree was selected out, a black layer was added between this layer and the old one, replacing the yellow tree with black.
A copy of the layer above the black layer had its contrast increased, and this was combined using soft light.
Then it was sized down to the size you see here. That looked nicer and also had the effect of taking away the individual remaining yellow pixels that were still awkwardly remaining from the tree.

The pink-ness is from the sky being nearly but not entirely clear, there was a soft, thin cloud that wasn't visible until the 30 sec exposures, all of which it was in.
