So you've played with lenses, mirrors, and built an optical bench. Want to make a real telescope? In this experiment, you'll build a Newtonian and a refractor telescope using your optical bench.
Materials:
- optical bench
- index card or white wall
- two double-convex lenses
- concave mirror
- popsicle stick
- mirror
- paper clip
- flash light
- black garbage bag
- scissors or razor
- rubber band
- wax paper
- hot glue
Yes you can – the larger the lenses/mirrors, the more light your telescope will be able to collect and the brighter the images you’ll see!
can the mirrors be 50mm diameter 38mm diameter
