the brightest star in the constellation has an apparent brightness of 3.95mag. It is one of the magnificent triple stars discovered in 1781 by W. Herschel, all of whose blue-white components can be distinguished even with small telescopes as a tiny triangle. The two components of brightness 4.7mag and 5.2mag are located 7.3" apart. The 6.1mag guide lies at a distance of 2.8" from the first component. The system is about 700 light years away. With a larger telescope, we can still detect a 12mag star at a distance of 25.9". This entire system is referred to as 11 Mon.
