This sequence of photos was taken on a 10.2 MPixel Nikon D200 SLR digital camera mounted on a Celestron CG Equatorial manual polar mount, driven by an analog clock drive manually aligned to Polaris. I used an 8 stop Neutral density filter. The exposures varied from the initial picture (1/8000, F-22) to the final exposure with the filter on (1/160th at F5.6). The final picture taken without the filter was F8 at 1/500th and was digitally corrected for saturation.
