Build Your Own Telescope: A Step-by-Step Guide to Stargazing

This proposal outlines the process of constructing a simple telescope using basic materials such as timber, carton, lenses, nails, glue, and packing materials. The guide includes detailed steps for cutting and assembling the telescope, as well as calculating the focal lengths for the objective and ocular lenses. This hands-on project not only fosters creativity but also enhances understanding of optical principles. By following these instructions, you will be able to create a functional telescope for stargazing, enriching your appreciation of the night sky.

  2. Presentation Proposal Telescope Star The materials to make telescope : • Timber • Carton • Lens • Nail • Glue • Pack suttle cock

  3. How to make telescope : • Cut 3 timbers with the long 120 cm. • Arranged the 3 timbers for buffer the telescope. • Stick the carton to pack suttle cock agree with focus (Fob + Fok). • Cut the carton. • Stick on the timber. • Enter telescope in the stick. • Pair the lens in telescope.

  4. The picture of star telescope

  5. Objective Lens : Distance shadow : 20 cm Distance object : 18 cm Diameter : 5 cm • Okuler Lens : Distance shadow : 50 cm Distance object : 73 cm Diameter : 5 cm

  6. Look for Objective Lens 1/f = 1/s + 1/s’ = 1/18 + 1/20 = 10/180 + 9/180 = 19/180 F = 180/19 = 9,47

  7. Look for Okuler Lens 1/f = 1/s + 1/s’ = 1/73 + 1/50 = 50/3650 + 73/3650 = 123/3650 F = 3650/123 = 29,674 D = Lob + Lok = 9,47 + 29,674 = 39,144
