Revisiting on a night with sub-arcsecond seeing, the two components split with no trouble, dark sky between, two nearly equal yellow stars quite close at 1.3", to use the language of Smyth and other classic double star observers... A quite delicate and fine double.
Parallax and proper motion data for the two stars are nearly identical, without doubt a true binary pair
