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.![]() |
