Antares B (the companion) is only 2.9 arcseconds away so I had to use an 'off sided' aperture mask to cut down on the glare of the main star washing out the visual split. Rotate the mask until the glare was not apparent on one side of Antares where it's companion was lurking. Can't remember what magnification I used now. You'll certainly need good seeing & Antares high in the sky.
After that, try splitting Sirius
