Magnification: 27x, 91x, 137x, 164x, 205x

 Located at 8:45pm PST. Had to get to 137x to begin to see a figure "8". Adding a little power to 164x gave me a clean but tight split and at 205x it was just a little easier but also dimmer. A fun little nut. Then I looked up through the finderscope and saw I was looking through quite a knot of branches! Now I wonder how tough of a nut it would be without a wood filter!
