Looks abstract with this magnification, very cool. Nice job with the stack, looks pretty clean. Good sharpness, there is some nice textures and details. There is some fringing on some edges but its not too severe and easy to fix if you decide to do so. Overall its a good image, nice work
Thanks! The 18-300+Raynox combination is not the sharpest macro lens, and I have pushed it to the edge (300 mm, about 2.3:1 reproduction ratio). It performs better than I expected however. It is sharper at around 150 mm (1:1)
