A quick tutorial on magnitudes. The magnitude scale is an inverse logarithmic scale, meaning as the magnitudes increase, the magnitude or brightness of an object decreases by a factor of about 2.5. The dimmest object that the human eye can see is about 6th magnitude on optimum conditions, dark skies, away from the city, city lights, things like that. A magnitude 5 object is 2.5 times brighter than a magnitude 6 object, while a magnitude 7 object is 2.5 times dimmer. The scale is actually designed so that every 5 magnitudes is 100 times differential in brightness between the objects. So a magnitude 1 object, which is 5 times, 5 magnitudes brighter than a magnitude 6 object is actually 100 times brighter. Keep an ear out when I talk about Saturn and Neptune coming up.
