DIY telescope simple tutorial
1, prepare the tube, the most primitive and simple telescope, with a tube as the tube, a lens in front as the objective lens, and a lens in the back as the eyepiece. The diameter of the objective lens determines the aperture of the telescope, that is, the thickness of the tube that needs to be prepared (inner diameter) the focal length of the lens determines the length of the tube tube, and the length of the tube that needs to be prepared needs to be greater than the focal length.
2, achromatic, in order to eliminate the color difference, we use two materials with different refractive indices to combine into achromatic lenses.
3, mirror tube selection, you can directly select the appropriate VPC water pipe for simple assembly, you can also use 3D printing, the structure will be more reasonable, the operation is also simpler.
