Star Magnitudes - Stargazing
The stars of Ursa Minor is a good constellation to determine how faint of a star can be observed. On star maps bright stars are represented with large dots while dimmer stars are represented with smaller dots. The brightness of the stars of Ursa Minor get fainter starting with Polaris at 2.0 magnitude which is located on the right side of the below star maps.
