And before anyone takes the trouble to point this out: Yes, I know the Herald-Bobroff includes DS symbols indicating relative separation for multiple stars, but it doesn't list identification (like Struve numbers) for them. Variable stars AND multiple stars are indicated on all the major atlases, but with no identification for multiples and rarely any for variables. And frequently, for reasons which totally escape me, atlases will indicate doubles with impossibly close separations (less than .5 arc seconds, etc.) Like a casual observer is going to notice a sub-arc second double while searching for a DSO!
