It was the American astronomer Charles B. Stephenson (1929 l 2001) who in 1959 tried to show that a group of stars that included Delta 1 Lyr and Delta 2 Lyr formed an open cluster, now better known as Delta Lyrae Cluster or Stephenson 1 (https://iopscience.i.../10.1086/127349). It was not until 1968 that this was finally confirmed (http://articles.adsabs.harvard.edu/pdf/1968ApJ...152...77E).
The attached sketch dates from 17/07/2021. Only a limited number of stars of the more than 65 members were visible with the 80 mm refractor. The moon (56 %), low on the horizon in the south-west will also have influenced the lesser visibility.
Delta 1 Lyr or 11 Lyr
AB: 5.5/9.9 175.3" 20°
The A component of Delta 1 Lyr, has a blue-white hue, the B component is white.
Delta 2 Lyr or 12 Lyr
AB: 4.3/11.2 86.3" 349°
AD: 4.46/8.47 193.1 210°
The A component of Delta 2 Lyr is light orange, the D component is white. The B component was not to be found at the presumed location, searched for using the Meade astrometric eyepiece.
The position angles of both doubles, AB & AD, differ +/- 190° and therefore 11 Lyr AB and 12 Lyr AD are oriented +/- parallel to each other but in opposite directions.
