[QUOTE="WayneF, post: 464370, member: 12496"] I strongly doubt that any of your single exposures show that effect. Lenses don't cause moire, but pixel patterns do. Your case is surely caused by slight misalignment of the pixels in multiple image layers, image pixels not precisely aligned. My wild guess is this pattern might be caused by doing lens distortion corrections before stacking them, so that some pixels in some layers get shifted differently, no longer perfectly registered when stacked? Try turning that feature off. [/QUOTE]
