Canes Venatici, the hound dogs, is very unnoticeable and minor constellation positioned at south of the handle of the Big Dipper.
The constellation is formed only two stars of alpha and beta CVn, was introduced by J. Hevelius in 1690.
It represents the two dogs of Asterion and Chara, held on a leash by Bootes as they chase the Big Bear (Ursa Major) around the North Pole.|
Alpha Canum Venaticorum with the second magnitude is well known called Col Caroli, meaning of the Heart of Charles. This name was given by Edmund Halley, naming it after King Charles II after the restoration of the monarchy in Britain in 1660. The constellation chart in the left shows the Heart with the crown put on at the star of Col Caroli.
The constellation has many bright galaxies in the outer space, and the Col Caroli is the good mark to search those deep sky objects.
