WebDec 10, 2015 · Transmissive telescopes are by their nature quite long, with a distance between the two lenses that is many times larger than the diameter of the main lens. A transmissive telescope with a 100 meter diameter lens would need to be thousands of meters long. This does not seem, upon first consideration, like a good thing. WebMay 28, 2024 · If you use both convex lenses, the distance between them need to be close to the sum of their focal lengths, F + f. Start there and adjust it slightly for best results. If you use a concave lens for the eyepiece, then the distance between lenses needs to be the difference of their focal lengths, F - f.
