A closer pair than the last two, still able to split it at low power. The primary was blue, the secondary I couldn’t make out any color. Flanked by 2 rather faint stars, forming a very flat triangle. The secondary points almost straight up from the base of this triangle.  I measured the separation at 6” and tried to measure the PA, but every time I kept coming up about 10 degrees off, so I decided to bag that.
