If the magnifying glasses are the same size, the telescope won’t work.
You should now have two lengths of corrugated paper. One piece should be slightly larger than the other.
The images will be upside down, since astronomers don’t care about up and down in space (there is no up or down in space, after all). if you wish to align the image with gravity, you can use two prisms aligned in an “N” shape to correct the image, but you will have to re-position the lenses.
Lenses should be a different focal length. For best results get a concave-convex lens with a diameter of 49 mm, and a focal length of 1,350 mm and a plano-concave lens with a diameter of 49 mm, and a focal length of 152 mm. It’s very easy to order lenses off the internet and they aren’t very expensive. You can get the pair of lenses for about $16. The coping saw is the most effective for making clean, straight lines, but you can use any other kind of saw or cutting device if you need to.
The spacers hold the second lens in place at the end of the outer section of the mailing tube.
You’ll also need to the make holes at the end of the outer tube for the eyepiece and the cap.
