Got this one in the same bino field of view as Albireo, although it actually lies just across the border in Lyra. 3 Vul is to the East. Easy to split, but both components roughly the same brightness. No colour discernible. Averted vision not required. I estimate northerly component to be the brighter, so this would put PA at 150 degrees or so. In fact, 33 Doubles lists this as PA 3 degrees, so I guess the southerly component must be the brighter. SMP numbers agree (S component: 7.35, N component: 7.31, putting them I think at 4% difference in brightness: no wonder I couldn't tell them apart!).

Seen and split, but a bit faint. OSS 181 is in very good company because on the edge of the same FOV we can see the bright and beautiful Albireo. The bright and wide double Alpha Vul can also be seen in this field.
