Open cluster types

• Type A: Rich starfield, with different brightness. Little concentrated, higher concentration in comparison with the environment.

• Type B: Different brightness. Little concentrated, higher concentration in comparison with the environment.

• Type C: Poor starfield, with different brightness. Little concentrated, higher concentration in comparison with the environment.

• Type D: Rich number of stars, higher concentration towards the center. Very high concentration of stars.

• Type E: Rich number of stars, poorly concentrated. Concentration higher than the environment. The stars are almost equally bright.

• Type F: Open cluster can only be detected by the similar brightness or color of the stars. Concentration is similar to the environment.

• Type G: Even using a high magnification, this is a compact open cluster. A lot of faint stars, close by each other.

• Type H: Very few stars visible. Concentration is not really higher than the environment. Impossible to say which stars are part of the open cluster.

• Type I: Even using a very high magnification, this is a compact open cluster. Very few and faint stars.

• Type X : Open cluster can not be characterized.
