The observation of galaxies with a telescope offers a level of difficulty in knowing their brilliance in the sky. The visual magnitude gives the brightness information as if the galaxy were a star in the sky. The surface magnitude distributes this brightness over the entire surface of the galaxy, offering a clue to the level of difficulty of its observation. Mag Galaxy transforms visual magnitude into areal magnitude for your galaxy observations.
