edited in LightRoom and Stacked in StarStax sw

First good star trail image I have taken at Death Valley, CA. in the vast open, clear sky of endless bright twinkling stars. those concentric circles around the focused and fixed North Star, Polaris, look good.
This is an approx. 40 mins exposure of about 78 good images for 20 sec each, with a 22 mm lens at f2 aperture. Stacked in StarStax sw.
I am happy enough but missing a good foreground here. Next time.
