written by the University of Oregon Physics Department
This activity asks students   to observe the images of three spiral galaxies of different surface brightnesses. Each of the loaded images is active in the sense that you can place a rectangular aperture on them and determine the flux. The flux through the aperture equals the galaxy flux + the sky flux. Hence to determine the galaxy flux you need to put an aperture on the sky background (where there is little or no galaxy light) and measure that.
