 I'll demonstrate the use of the color and averted vision card. This card can be used at night at the telescope or in a darkened room. Of course to shoot this video we require a lot of light, so in the video you will not see what you would see with your eyes in the dark. Please consider this only a demonstration of how to use the card. First let's look at the color side of the card. We're looking at a distant galaxy called the Whirlpool Galaxy. I thought I'd see more color. Most of the pictures you see in magazines are in color, so it might be disappointing not to see much color in the telescope. Our eyes just cannot detect much color in dim light. Here, can you tell me what colors these squares are? When we look through the scope, for the most part our eyes only see shades of gray. What colors do you see? Mostly gray. There might be some green. Okay, now what colors do you see? Nicely blue and red and some yellow. We don't have as many color receptors in our eyes as black and white receptors. Also our eyes colors receptors are not as sensitive. We need a lot of light for our eyes colors receptors to detect any color at all. When we look at dim objects that are far out in space there is so little light reaching us that only our black and white receptors can detect the light. Take another look. That galaxy sure is dim. It looks just like a fuzzy patch. You're right. Only a little of its light is reaching us. Let me show you a way to use the part of your eye that is most sensitive to light so you can see more detail. We'll use a technique called averted vision. It's really easy. Close one eye. Look directly at the galaxy image in the middle. Now look at the black dot away from your nose. I see that your right eye is open so you would look to the dot on the right. The image might appear to be a little brighter but the effect works better in the telescope. When you look into the telescope eyepiece at the dim object look to the side away from your nose about as close to the object as this dot is to this photo. The object you're viewing will appear brighter and you'll see a little more detail. That is better. This is important. If you look in the direction of the dot toward your nose you are centering your eyes blind spot over the image making the object disappear. Look at your vision in the correct direction away from your nose. There's more information on why this works in the manual.
