The brightest star of the constellation has a magnitude of 1.1 and is the 13th brightest star in the sky. In a telescope, we can distinguish it as two sparkling blue-white components separated by 4.4". They have magnitudes of 0.8 and 2.1, and we can separate them with a 60 mm telescope. The system is located at a distance of 370 light-years. We can find a third unrelated component with a magnitude of 5 in a refractor 90" away.
