I have used Sequator for these panorama wide field shots and it does a good job. I have also just aligned and stacked in PS and not worried too much about the tracking blurring the trees a little. Sequator will produce a full 360, there are many options depending on your aim.
The iceman has tuturiols for stacking a flattened shot with a separate foreground but elsewhere here in the nightscapes section you will see great shot with a tracked foreground made crisp using the foreground features of Sequator , that I am yet to try , but it looks stunning.
