Nice and easy split. Took a while to find Scorpius since I'm unfamiliar with it. Had to catch this session while the top of Scorpius was between a tree and Butch's house. Primary appears yellow.

A double-double! ξ Scorpii's sibling is faint and hard to see. Struve 1999 has both stars appear at very similar magnitudes.

Faint. This is likely from being so low on the horizon. AV is helping discern the shape, but I'm noticing more variation from AV than usual. Depending on where I look using AV, the target appears either circular, or a sharp vertical oval. I've seen variation when using AV before, but nothing like this!
