Got a beautiful view of Antares B last night using my 5" refractor. Employing 236x the secondary was pulled cleanly away from the primary appearing as a vivid almost neon like lime green airy disk. The contrast between the orange primary and the green secondary was stunning!. I am using a Baader Fringe Killer with the F9.3 achro and the attenuation of the shorter wavelengths apparently made the secondary ''greener" than it would normally appear. Really beautiful contrast!
