I finally had a chance, and the energy, to get out last night and try the K-1 out for some night work, with the Sigma 16mm f2.8 Rectilinear Fisheye mounted. This was my first ever digital star trails effort, only having use Kodachrome before, many years ago (I gotta find those slides and copy them with the K-1).
Combined with StarStax, post processed in Photoshop.
Same set, squeezed a bit differently each time, resulted in slightly different colors in the stars.
I have plenty of room for improvement, and will get out again, and try for more shots over a longer period of time.
Next up, Racer tries that pesky Astrotracer feature.
Stay tuned . . . . .
