Another experiment with focus stacking - only 3 images this time. Again, not as clear as I'd like. The largest stars are about 4mm in diameter. They are fossilized crinoid (sea lily) stem segments in gray limestone. Easy to miss when hiking unless you're crawling on the ground - collected from a top secret location in the Muddy Mountains.
