This is a difficult double because of the magnitude difference between the stars. With a separation of 8.9", the white primary has a magnitude of 3.1, but the blue-white secondary is only at 8.2. At 122X in an 8" scope, the split is more obvious and the companion appears a little bluer. 81X may however give the best view, because the stars seem to glisten more. |
