Years ago I made an 'apodizing' filter using window screen, which is "supposed" to help with double stars. You might do a search to see if this is something that would interest you.
Easy to make and it works well.

At these separations doubles would not qualify as close pair where ring brightness might matter. You might loose the dark space at the Raleigh limit observing a classic Raleigh pair and Dawes splits would be more difficult. Wider doubles might be more aesthetically pleasing, however, as well as larger planetary details.
Another trick to observing Sirius pup is to have very clean optics to reduce glare. Some folks have uses square aperture mask to change the shape of diffraction. But, a good neutral density filter might help, too.
