a close binary (6mag and 6.4mag components at 0.6"- 1.4" separation over 165 years) that is a test for larger amateur telescopes. It is 124 light years away. The main component is many times brighter than our Sun. The guide, on the other hand, is very similar to the Sun. It is of the same spectral type and has the same colour - a nice yellow.
