According to SkyTools, the AB pair's separation is 0".68 for the current epoch. Given tonight's seeing it is not surprising that I could not split, notch, or even elongate them. However, the C star, H 4 104, was visible. In fact, it appeared to be double but its 11th-magnitude "companion" is apparently not associated with it.

Always a close pair, very bright, but closing now and will get very difficult in a couple of years. Tough tonight as it is slipping into the western horizon and just not enough altitude to get above to poor seeing. Both stars showed spectrum spreading and elongation, a narrow band filter would have helped or one of those fancy split prisms. Measured, poorly, 0.68 sec at 301+or-6 deg PA.
