a double star approximately on the boundary with the neighbouring constellation of the Little Lion. The main white component reaches a brightness of 3.9mag, the rusty guide 6.6mag. They are 2.7" apart and their distance from Earth is about 117 light years. The main star has about 32 times the luminosity of the Sun. At a distance of about 88" from this star we see another guide star of stellar magnitude 11mag, but it only projects into this region by chance. It is advisable to use at least 100x magnification.
