Deb, I enjoyed your post also. Unfortunately, I deleted it accidentally. You wrote that you used a SCT, IIRC? Next time, try an apodizing mask with this scope (or any with a large central obstruction). This will channel some of the diffraction energy out of the central spot, and might make some of the really tight pairs more easily observed, especially where there is a gross magnitude difference.
