Is every constellation a galaxy?

Constellation is the projection of the stars in a certain sky area on the celestial sphere. There are single, double or multiple stars in the constellations. All the stars visible to the naked eye are members of the Milky Way. There are many extragalactic galaxies like the Milky Way in the projection area of each constellation, but most extragalactic galaxies are invisible to the naked eye. The ones you can see are also fuzzy highlights, which are obviously different from the stars. Because of the projection relationship, there is no question of whether the constellation is big or the galaxy is big.
