This is a contiuation of a series of 5 images, the first 3 of which were posted yesterday. These images, together, behave as a fractal. The last two pics in the series are taken at 5x lifesize and 9-10 times lifesize (based on approximation of actual focal lenth of my Canon 65mm MP-e at 5x with 134mm of extension added) Hope you enjoy.
@5x

@9-10x

Yes, very unusual spines on Mammillaria lutheyi. The spine itself has a radiating "parachute" of additional spines at it's tip. Something so far unique within the Cactaceae I believe.

It sure is a very unique looking cactus. I bet you are glad you did not throw it away on first impulse. And again the stacks are wonderfully done.

Thanks Doug. The best thing for me about macro is the sense of discovery.

I am working on adding to the series by on taking a higher mag shot that will isolate on of the little umbrellas. I need to get my hands on some Higher mag optics first. Just what I need, more glass.
