Sirius
(/ˈsɪriəs/, a romanization of Greek Σείριος, Seirios, lit. "glowing" or "scorching") is a star system and the brightest star in the Earth's night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The system has the Bayer designation Alpha Canis Majoris (α CMa). What the naked eye perceives as a single star is a binary star system, consisting of a white main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, called Sirius B. The distance separating Sirius A from its companion varies between 8.2 and 31.5 AU.(Wikipedia)

I should have known about B companion and I'm sorry about that. I don't see anything else but only one bright star.

I wonder if it is the star at 8 o'clock.
Which way is up and which way is east on your brilliant picture?
It ought to be easy to figure out once we know that information.
