The light is fine... The problem is with your eyes!<br /><br />Human eyes have two kinds of photorecoeptors: rods and cones. The rods pick up intensity without color, like a black and white camera. Each of the cones pick up one of 3 colorss. Rods are more sensitive to low light levels.<br /><br />There isn't enough light coming through the small telescope to activate the cones. The rods can determine Saturn's shape and grey-level, but not the color.<br /><br />Have you ever noticed that it is very difficult to see colors in moonlight? This is exactly the same effect. We evolved this way because it was important to sense danger at night and pick ripe fruit by day.<br /><br />You can see color through a larger telescope because there is enough light gathered by the telescope for your cones to start working.<br /><br />The fovea, the very center of your vision, is jam-packed with cones, and has few rods. Since the cones aren't being activated by the low light level, it is hard to look at Saturn through the telescope if you look directly at it. However, if you move your eyes very slightly, so that you are looking directly at the black sky NEXT TO Saturn, you might find it easier to see. This technique is called "averted vision".<br /><br />Cameras can see color in telescopes because the longer the sensor (film, CCD) stares at the target, the more photons are counted on the image. Eyes don't work that way. You won't be able to see the color, no matter how long you stare.
