| STFA 26 | 21 Boo = iot Boo. STTA128. A is a spectroscopic binary and a Delta | |
| Scuti-type variable, P = 0.027d. B is BD+52@1785. | ||
| Struve suspected a close companion to A (1836.28, 149.9deg, 0".3) | StF1837 | |
| as did Smyth (1838.19, 195.0deg, 0".5) but this supposed pair | Smy1844 | |
| has never been confirmed with larger telescopes. | ||
