| BLL 42 | Chi Cyg. A is a Mira-type variable. | |
| Smyth published a measure for an additional 9th magnitude component | Smy1844 | |
| (1835.67, 72.9deg, 25".7) and noted similar measures by Herschel | H__1906A | |
| (1779, 24".8) and South & Herschel (1822.49, 63.3deg, 25".5). However, | SHJ1906A | |
| ALADIN indicates nothing at the purported location of this object. | ||
| These measures appear to have been assigned to 19464+3344 STF2580AB, | ||
| instead. |
