Materials that you are going to need : Magnifying glass, Masking tape, Flash-lamp , Thin sheet of paper, a couple of reading glass with low numbers, yardstick, and an aid. Tape the reading glasses to the yardstick ensuring one lens is out on the side. Place the flash-lamp on a stand about 12 feet away. Shine the light at the lens that's sticking out. Place the thin piece of paper on the side across from the torch. Run away from the paper till you see a tiny image of the flash-lamp on the paper. Tell your assistant take the paper to the focus. Go round to the back side of the paper and check the image in your magnifying glass. Adjust till the image from the flash-lamp is enlarged. Take the paper away and keep looking thought the eyepiece or lens. The image will be brighter since the paper was removed. Look at other varied items close to the flash-lamp. Move the eyepiece or lens up and down or side to side to get a good image. With a bit of time and effort, you may have your own telescope running in a couple of minutes.

You'll see how light helps to focus the image and that lower magnification can provide you with a more clear image. You also have an aid who can try different objects to find out how clear they can be viewed and whether the magnifying glass must be moved in or out. This is a simple experiment not requiring power tools or difficult schematics. You can learn so much from this experiment that may tell you if this is something that you want to pursue as a spare time pursuit. Do not get irritated that it could take a couple of times to get the image right, but when you learn the skill of it, there are such a lot of neat objects out there to view.
