150MCT 10 waves Extra Focal cropped
Polaris at 16 degrees above the horizon (not good seeing) with a handheld DSLR with 12mm Ortho at about 160x and 5.2x camera zoom. Outside focus about 10 waves. Low contrast, slightly undercorrected. Secondary hole looks smaller than it really is because some of the fuzziness was bleeding into the shadow. But, the central ring is a tad brighter. Extrafocal image is roughly the same size as the intrafocal image.
