I have some "Super Moon" at perigee pictures from 5 May 2012, on the 8' newtonian telescope made with DSLR Nikon.
What our eyes perceives as a single star is actually a binary star: Sirius A and Sirius B A1V (A) / DA2 (B). These two stars are visible in the video below. Distance that separates the two stars, varies between 8.1 and 31.5 AU.
