Not split, but the star seems oblong in the correct direction. The 1.5 mag difference is to blame here. Guess at measurement; 0.49 sec at 145 deg PA. Will try this one again, hopefully in better air. More data to do, will post later.

Tried this one again with the same results, just elongated, not even a figure 8. But the elongation matched my previous sights, so maybe real. Poor guess measurement; 0.44 sec at 141 deg PA.
