How Do You Make An Astronomical Telescope?
A simple telescope enlarges an image by flipping it on it’s way to your eye. Extra lenses are needed to reflip the image so you see things right-side up. Since stars and planets have no “right side up” orientation, an astronomical telescope doesn’t need the extra lenses and length required to right the image. The fewer lenses light passes through, the sharper and brighter the image. Isaac Newton’s reflector telescope design takes advantage of this with a simple design that maximizes magnification while minimizing distortion and light loss. Position the mirror on the mirror cell mount and gently tighten the mounting brackets. Do not adjust the collimating screws. Test fit the primary mirror assembly into the base end of the Sonotube so the bottom of the cell is even with the bottom of the tube. Measure the distance from the base of the mirror cell to the center of the surface of the mirror. Measure the same distance from the bottom end of the sonotube and mark the side. Remove the mirro
