150MCT 10 waves Intra 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. Intrafocal at about 10 waves, slightly less. Better contrast than extrafocal image, slightly undercorrected. Secondary hole looks larger than extrafocal image. Extrafocal image is roughly the same size as the intrafocal image. Scope is collimated, I think the camera was skewed a bit.
